Write C program to display the first five odd numbers using goto statement

goto syntax in C Syntax:- goto label_name; A statement label is defined in exactly the same way as a variable name, which is a sequence of letters and digits, the first of which must be a letter. The statement liable must be followed by a colon (:). Like other statements, the goto statement ends with a semicolon. The goto is an unconditional branching statement and its use is discouraged in structured programming. In a language that provides the various loop statements like ‘for’, ‘while’, and ‘do-while’ as well as the switch statement, there is normally no need to use the ‘goto’ statement. Often, a break statement or a continue statement can eliminate the need for a goto statement. Because the goto statement can interfere with the normal sequence of processing, it makes a program more difficult to read and maintain. Examples of C goto Program1:- Print first N natural numbers in C programming using the goto statement. #include int main() { int n, i=1; printf("Enter a number: "); scanf("%d",&n); start: printf("%d\t",i); i++; if(i int main() { int n, sum=0; start: printf("Enter a number: "); scanf("%d",&n); if(n<0) goto end; sum = sum + n; goto start; end: printf("Sum = %d",sum); return 0; } Output:- Enter a number: 10 Enter a number: 15 Enter a number: -5 Sum = 25 In this program, two goto statements are used. The first goto statement (goto end and label end) works as a break statement and the second goto statement (goto start and label start) works as a loop. Use of goto statement The goto statement is used:- To execute a group of statements repeatedly for a particular number of times. To come out of several nested loops at one stroke. Program3:- Write a program to find factorial of a given number in C programming using the goto statement. #include int main() { int num; long fact = 1; printf("Enter a number: "); scanf("%d",&num); if(num<0) goto end; for(int i=1; i<=num; i++) fact = fact * i; printf("Factorial of %d is = %ld", num, fact); end: return 0; } Output:- Enter a number: 5 Factorial of 5 is = 120 In the above program for calculating the factorial, we used a goto statement and for loop. We can do the same without using for loop also. The below program is without for loop. #include int main() { int num; long fact = 1; printf("Enter a number: "); scanf("%d",&num); if(num<0) goto end; int i=1; loop: fact = fact * i; i++; if(i<=num) goto loop; printf("Factorial of %d is = %ld", num, fact); end: return 0; } Output:- Enter a number: 5 Factorial of 5 is = 120 Enter a number: 6 Factorial of 6 is = 720 Enter a number: 7 Factorial of 7 is = 5040 Note:- Generally, we don’t use the goto statement in C programming. It is recommended to use loops instead of using goto statement. Use goto statement, only if loops can’t do that operation. If you enjoyed this post, share it with your friends.

How to calculate adult age in C language while loop?

Given accepted date and bearing date, acquisition the present age. Examples: Input : Bearing date = 07/09/1996 Present date = 07/12/2017 Output : Present Age = Years: 21 Months: 3 Days: 0 t Age = Years: 7 Months: 11 Days: 21 Recommended: Please try your access on {IDE} first, afore affective on to the solution. While artful the aberration in two dates we charge to aloof accumulate clue of two altitude that will do. If the accepted date is beneath than that of the bearing date, again that ages is not counted, and for abacus dates we add cardinal of ages canicule to the accepted date so as to get the aberration in the dates. If the accepted ages is beneath than the bearing month, again the accepted year is not taken into calculation as this year has not been completed and for accepting the aberration of months, we decrease by abacus 12 to the accepted month. At the end we aloof charge to decrease the days, months and years to get the aberration afterwards the two altitude are dealt with. Below is the accomplishing of the aloft access : // c program for age calculator #include #include // function to calculate current age void findAge(int current_date, int current_month, int current_year, int birth_date, int birth_month, int birth_year) { // days of every month int month[] = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 }; // if birth date is greater then current birth // month then do not count this month and add 30 // to the date so as to subtract the date and // get the remaining days if (birth_date > current_date) { current_date = current_date + month[birth_month - 1]; current_month = current_month - 1; } // if birth month exceeds current month, then do // not count this year and add 12 to the month so // that we can subtract and find out the difference if (birth_month > current_month) { current_year = current_year - 1; current_month = current_month + 12; } // calculate date, month, year int calculated_date = current_date - birth_date; int calculated_month = current_month - birth_month; int calculated_year = current_year - birth_year; // print the present age printf("Present Age\nYears: %d Months: %d Days:" " %d\n", calculated_year, calculated_month, calculated_date); } // driver code to check the above function int main() { // current dd// mm/yyyy int current_date = 7; int current_month = 12; int current_year = 2017; // birth dd// mm// yyyy int birth_date = 16; int birth_month = 12; int birth_year = 2009; // function call to print age findAge(current_date, current_month, current_year, birth_date, birth_month, birth_year); return 0; } Output: Present Age Years: 7 Months: 11 Days: 22

How to use inbuilt system defined sorting algorithm in C language?

This article will will put forth an interesting and an important topic that is Sorting Algorithms In C.Following pointers will be covered in this article, Bubble Sort Insertion Sort Selection Sort Quick Sort Merge Sort In simple word, sorting means arranging the given elements or data in an ordered sequence. The main purpose of sorting is to easily & quickly locate an element in a sorted list & design an efficient algorithm around it. In this blog we will understand different sorting algorithms & how to implement them in C. So let us get started then, Bubble Sort Bubble Sort is a simple sorting algorithm which repeatedly compares the adjacent elements of the given array & swaps them if they are in wrong order. Suppose we have an array X which contains n elements which needs to be sorted using Bubble Sort. The sorting works as: Pass 1: X[0] & X[1] are compared, and swapped if X[0] > X[1] X[1] & X[2] are compared, and swapped if X[1] > X[2] X[2] & X[3] are compared, and swapped if X[2] > X[3] and so on… At the end of pass 1, the largest element of the list is placed at the highest index of the list. Pass 2: X[0] & X[1] are compared, and swapped if X[0] > X[1] X[1] & X[2] are compared, and swapped if X[1] > X[2] X[2] & X[3] are compared, and swapped if X[2] > X[3] and so on… At the end of Pass 2 the second largest element of the list is placed at the second highest index of the list. Pass n-1: X[0] & X[1] are compared, and swapped if X[0] > X[1] X[1] & X[2] are compared, and swapped if X[1] > X[2] X[2] & X[3] are compared, and swapped if X[2] > X[3] and so on… At the end of this pass. The smallest element of the list is placed at the first index of the list.

The principle behind insertion sort is to take one element, iterate through the sorted array & find its correct position in the sorted array. Step 1 − If the element is the first one, it is already sorted. Step 2 – Move to next element Step 3 − Compare the current element with all elements in the sorted array Step 4 – If the element in the sorted array is smaller than the current element, iterate to the next element. Otherwise, shift all the greater element in the array by one position towards right Step 5 − Insert the value at the correct position Step 6 − Repeat until the complete list is sorted Insertion Sort Program in C 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 #include #include // Insertion Sort Function void insertionSort(int array[], int n) { int i, element, j; for (i = 1; i < n; i++) { element = array[i]; j = i - 1; while (j >= 0 && array[j] > element) { array[j + 1] = array[j]; j = j - 1; } array[j + 1] = element; } } // Function to print the elements of an array void printArray(int array[], int n) { int i; for (i = 0; i < n; i++) printf("%d ", array[i]); printf("n"); } // Main Function int main() { int array[] = { 122, 17, 93, 3, 56 }; int n = sizeof(array) / sizeof(array[0]); insertionSort(array, n); printArray(array, n); return 0; } Output Output- Sorting Program in C- RHNCOMPUTER Moving on with this article on Sorting Algorithms In C, Selection Sort Selection Sort repeatedly searches for the smallest element from the unsorted part of the array and places it at the end of sorted part of the array. Selection sort first finds the smallest element in the unsorted array and swaps it with the first element. Then it finds the second smallest element in the unsorted array and swaps it with the second element, and the algorithm keeps doing this until the entire array is sorted.

QuickSort algorithm partitions the complete array around the pivot element. Pivot element can be picked in mulitple ways: First element as pivot Last element as pivot Median element as pivot Random element as pivot In this blog we will be picking the last element as pivot element. partition() is the key process behind the QuickSort algorithm. In partitioning, the pivot element plays an important role. Pivot is placed at its correct position in the sorted array, all the elements smaller than pivot is placed before it, and all the elements greater than pivot is placed after it. All this operation is completed in linear time. Then the array is divided in two parts from the pivot element (i.e. elements less than pivot & elements greater than pivot) & both the arrays are recursively sorted using Quicksort algorithm.

In Merge sort, we divide the array recursively in two halves, until each sub-array contains a single element, and then we merge the sub-array in a way that it results into a sorted array. merge() function merges two sorted sub-arrays into one, wherein it assumes that array[l .. n] and arr[n+1 .. r] are sorted.

How to write a function that works similar to scanf in C?

I accept actual frequently apparent bodies black others from application scanf and adage that there are bigger alternatives. However, all I end up seeing is either "don't use scanf" or "here's a actual architecture string", and never any examples of the "better alternatives" mentioned. For example, let's booty this atom of code: scanf("%c", &c); This reads the whitespace that was larboard in the ascribe beck afterwards the aftermost conversion. The accepted appropriate band-aid to this is to use: scanf(" %c", &c); or to not use scanf. Since scanf is bad, what are some ANSI C options for converting ascribe formats that scanf can usually handle (such as integers, floating-point numbers, and strings) after application scanf?

Why puts and gets used before printf scanf in C?

C gets() and puts() functions The gets() and puts() are declared in the header file stdio.h. Both the functions are involved in the input/output operations of the strings. C gets() function The gets() function enables the user to enter some characters followed by the enter key. All the characters entered by the user get stored in a character array. The null character is added to the array to make it a string. The gets() allows the user to enter the space-separated strings. It returns the string entered by the user. Declaration char[] gets(char[]); Reading string using gets() #include void main () { char s[30]; printf("Enter the string? "); gets(s); printf("You entered %s",s); } Output Enter the string? javatpoint is the best You entered javatpoint is the best The gets() function is risky to use since it doesn't perform any array bound checking and keep reading the characters until the new line (enter) is encountered. It suffers from buffer overflow, which can be avoided by using fgets(). The fgets() makes sure that not more than the maximum limit of characters are read. Consider the following example. #include void main() { char str[20]; printf("Enter the string? "); fgets(str, 20, stdin); printf("%s", str); } Output Enter the string? javatpoint is the best website javatpoint is the b C puts() function The puts() function is very much similar to printf() function. The puts() function is used to print the string on the console which is previously read by using gets() or scanf() function. The puts() function returns an integer value representing the number of characters being printed on the console. Since, it prints an additional newline character with the string, which moves the cursor to the new line on the console, the integer value returned by puts() will always be equal to the number of characters present in the string plus 1. ADVERTISEMENT Declaration int puts(char[]) Let's see an example to read a string using gets() and print it on the console using puts(). #include #include int main(){ char name[50]; printf("Enter your name: "); gets(name); //reads string from user printf("Your name is: "); puts(name); //displays string return 0; } Output: Enter your name: RHNCOMPUTER Your name is: RHNCOMPUTER
