[LC++]declaring and using manipulating global variables

[hursh]

Is this what you're after?

#include <iostream>

int i = 0;

void inc(){ i++; }

int main(){
         int x = 5;
         do{
                 inc();
                 std::cout << i << std::endl;
         }while(x--);
         return 0;
}
