I believe this is what you wanted..

#include<iostream>
using namespace std;

void f()
{
	int i = 20;
	cout << "\n" << "in f(),the value of i is:" << i;
	

}


int main()
{
	int i = 10;
	cout << "\n" << "in main(), the value of i is:" << i;
	f();
	cout << "\n" << " back in main(),the value of i is:" << i;
	return 0;
}

Tried Leaving everything as similar to original as possible

void main() // <--- Change this to int main() 

Also you would need to put void f() above int main (), so main() knows what f() does


P.S. use source code in format so its easier to read your code! Thanks!

see what tulu wrote and instead of void main() use int main() and before the last } inside main() use return 0;
