Using Goto function across different functions

Question

How can I use goto function across different functions .For ex ,

    main()
    {
      ....
      REACH:
      ......
    }

    void function()
    {
             


        

Answer 1

You can't. Think of this. There is a function A which is recursively calling another function B which in turn is calling A. Now, suppose that you put a goto statement from A to B. The question now becomes which instance of A do you want to go to which is undefined. Also, if no previous instance of A is defined, you have a bigger problem of no initialized variables in the function that are present before the label.

#include "bits/stdc++.h"
int i=0;
A(){
run:
    B();
}
B(){
if(i==10)
    goto run;
i++;
A();
}
