The goto statement is known as jump statement in C. As the name suggests, goto is used to transfer the program control to a predefined label.
The goto statment can be used to repeat some part of the code for a particular condition. It can also be used to break the multiple loops which can't be done by using a single break statement.
However, using goto is avoided these days since it makes the program less readable and complecated.
Syntax:
label:
//some part of the code;
goto label;
#include<stdio.h>
int main()
{
int num,i=1;
printf("Enter the number whose table you want to print?");
scanf("%d",&num);
table:
printf("%d x %d = %d\n",num,i,num*i);
i++;
if(i<=10)
goto table;
}
The only condition in which using goto is preferable is when we need to break the multiple loops using a single statement at the same time.
#include<stdio.h>
int main()
{
int i, j, k;
for(i=0;i<10;i++)
{
for(j=0;j<5;j++)
{
for(k=0;k<3;k++)
{
printf("%d %d %d\n",i,j,k);
if(j == 3)
{
goto out;
}
}
}
}
out:
printf("came out of the loop");
}
