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.
