However, The goto statement is rarely used because it makes program confusing, less readable and complex. Also, when this is used, the control of the program won’t be easy to trace, hence it makes testing and debugging difficult.

Syntax: go to statement

label_name:   
//some part of the code;   
goto label_name;

The label is an identifier. When the goto statement is encountered, the control of the program jumps to label: and starts executing the code.

Let's understand with a simple example.

Example 1: goto statement

#include <stdio.h> 
#include <conio.h> 
void main ()  
{  
    printf("Welcome to Protec\n");
    goto out;  //Here, goto statement is occurred
    printf("IT Training Center");
    printf("At Tara Market, beside Vishal MegaMart-Siwan");
    out:  
        printf("welcome2protec is a free online IT tutorial site!");    
    getch();  
 }  

Explanation: In this example, When the goto statement is encountered, the control of the program jumps to label_name, out: and starts executing the code (welcome2protec is a free online IT tutorial site!).

Example 2: goto Statement

#include <stdio.h> 
#include <conio.h> 
void main ()

    int marks;
    clrscr();
    printf("Please Enter  your marks:");
    scanf(""%d", &marks);  
    if(marks >= 50)  
    {  
       goto pass;  
    } 
    else
    {

    } 
    pass:
    printf("Congratulation! You have passed the exam.\n", num); 
    fail:
