Lets make one program to understand it.

#include<stdio.h>

void main()
{
 int i=1;

 if(i==1)
  goto one;
 else if(i==2)
  printf("2");
 else
  printf("Its nothing");

 one:
 printf("Avoid goto keyword");
}

Output

Why you should avoid goto statement in C?
It takes the control of the program anywhere and anytime which is not good for software development life cycle. In this cycle a program has to debug and re-test a lot of times. And with the use of goto keyword it makes very hard to debug the program.

This keyword is generally used to take the control outside the loop. That’s it. Otherwise you should avoid this keyword.
