Try this:

1. Create new project and create new c++ main file.

#include <stdio.h>
int main(int argc, char**argv) {
   int i;

   printf("Enter some integer: ");
   scanf("%d", &i);
   printf("i is %d\n", i);
   
   return i;
}

2. Make sure that 'Console Type' property of the project is set to Default or
'External Terminal' value. 

Exit status of the program is always displayed as '0' 


With 'Output Window (Input only)' it works just fine.
