#include

int x = 30;

int y = 40;

int z = 50;

void func()

{ x = x+1;

y = y+2;

z = z+ 3;

printf("func is x=%d, y=%d z=%d , x, y,z");

}

void func2()

{ int z = 20;

y = y+2;

z = z+ 3;

func();

printf("func2 is x=%d, y=%d z=%d , x, y,z");

}

int main(int main(int argc, char *argv[])

{

func2();

printf("main is x=%d, y=%d z=%d , x, y,z");

}

The question is if I move the global variables x, y, z to main(), how do I pass x and y to func2() from main and pass addresses of x, y, z from func2() to func(). I want to mimic a dynamic scope in C.
