getting address of particular instruction in a function

Question

I want to acquire the address of label1 in function main without calling function Func(int a,int b). How can this be done?

Code:

File1.c

int *ptr2;
int Func(int a, int b)
{
    int c;
    c = a+b;
    label1:
    ptr = (int*)&&label1;
    return c;
}

File2.c

#include<File1.c>
extern int *ptr2; 
int main()
{
    int *ptr,var;
    //var = Func(10,20);
    ptr = ptr2; 
}
