Question

#include <iostream>
#include <windows.h>
using namespace std;


int go_to(int x, int y)
{
  COORD c;
  c.X = x - 1;
  c.Y = y - 1;

  return  SetConsoleCursorPosition (GetStdHandle(STD_OUTPUT_HANDLE), c);
}

void main(){
  int a=1;

  while(a<10){
    a++;
    cout<<"work"<<endl;
    go_to(3,6);
    cout<<"work"<<endl;
  }
}

I’m not understand why this loop work only 1 time, maybe you know where is problem ?
I thing that problem is in Cord, but don’t know similar way to use CORD.

Answer 1

The variable a is only modified by the a++; line which increases its value by 1, and it isn’t passed into go_to(x,y), so it can’t be affected by that function.

Your loop will definitely run for values a={1 to 9}, calling go_to(3, 6) each time, and also printing work twice. I believe you’re mistaken if you think otherwise.
