'goto' Statement in C Language

← Previous Next →

In C goto statement is used as a jumping statement. Jumping means transferring program control from one statement to another statement in program. A level ( variable name ) is required to use goto statement in c program, level name can be any name except c keyword.

How goto looks like in C ..?

goto level_name;
............
............
............ // block of code
............
level_name:
statement;

What do you think about output..?

#include<stdio.h>
 int main()
  {
    int i=0;  
    top_level:
    i = i + 1;
    printf("%d", i); 
    if(i<=10)    
      {
        goto top_level; 
      }
     return 0;
  }

How to use 'goto' in C

To use goto statement, level is must.
level can be any variable name except c keyword and colon : is must required just after the level_name.
Example of level declaration - level_name:
to jump on level, goto keyword must followed by level_name.
Example of goto statement - goto level_name;
goto jumps program control on level_name position.
The place of goto and level_name declaration can be accoding to programmer and program requirement, they can be on top to bottom or bottom to top.
For best programming experince use goto statement with conditional statement, for example if statement.
In large program avoid to use goto statement.
Let's see some goto statement programs by taking some example.

goto statement example

#include<stdio.h>
 int main()
  {
    int i=0;  
    counting:
    i = i + 1;
    if(i<=10)    
      {
        if(i%2==0)    
        {
         printf("%d is even number\n", i);
         goto counting;
        }
       else
        {
         printf("%d is odd number\n", i);
         goto counting;
        }
      }
     return 0;
  }

Output

1 is odd number
2 is even number
3 is odd number
4 is even number
5 is odd number
6 is even number
7 is odd number
8 is even number
9 is odd number
10 is even number
