What is C unconditional jump statements?
C programming language allows jumping from one statement to another. It also supports break, continue, return and go to jump statements.
break
- It is a keyword which is used to terminate the loop (or) exit from the block.
- The control jumps to next statement after the loop (or) block.
- break is used with for, while, do-while and switch statement.
- When break is used in nested loops then, only the innermost loop is terminated.
The syntax for break statement is as follows −
Example
Following is the C program for break statement −
#include<stdio.h>
main( ){
int i;
for (i=1; i<=5; i++){
printf ("%d", i);
if (i==3)
break;
}
}Output
When the above program is executed, it produces the following output −
1 2 3
continue
The syntax for the continue statement is as follows −
Example
Following is the C program for the continue statement −
#include<stdio.h>
main( ){
int i;
for (i=1; i<=5; i++){
if (i==2)
continue;
printf("%d", i)
}
}Output
When the above program is executed, it produces the following output −
1 2 3 4 5
return
It terminates the execution of function and returns the control of calling function
The syntax for return statement is as follows −
return[expression/value];
Example
Following is the C program for the return statement −
#include<stdio.h>
main(){
int a,b,c;
printf("enter a and b value:");
scanf("%d%d",&a,&b);
c=a*b;
return(c);
}Output
When the above program is executed, it produces the following output −
enter a and b value:2 4 Process returned 8 (0x8)
goto
It is used after the normal sequence of program execution by transferring the control to some other part of program.
The syntax for the goto statement is as follows −
Example
Following is the C program for the goto statement −
#include<stdio.h>
main( ) {
printf("Hello");
goto l1;
printf("How are");
l1: printf("you");
}Output
When the above program is executed, it produces the following output −
Hello you
