Control Instructions - Programming

Q1:

Point out the error, if any in the while loop. 
#include<stdio.h>
int main()
{
    void fun();
    int i = 1;
    while(i <= 5)
    {
        printf('%d\n', i);
        if(i>2)
            goto here;
    }
return 0;
}
void fun()
{
    here:
    printf('It works');
}

A No Error: prints "It works"

B
Error: fun() cannot be accessed

C
Error: goto cannot takeover control to other function

D No error

ANS:A - No Error: prints "It works"

A label is used as the target of a goto statement, and that label must be within the same function as the goto statement. Syntax: goto <identifier> ;
Control is unconditionally transferred to the location of a local label specified by <identifier>.
Example:

#include <stdio.h>
int main()
{
    int i=1;
    while(i>0)
    {
        printf('%d', i++);
        if(i==5)
          goto mylabel;
    }
    mylabel:
    return 0;
}
Output: 1,2,3,4
