Thread: cout statement not working....i think...

ahhh...yeah this is really stupid but why is my program outputting zero for the variable pop?

Code:

#include <iostream>

int main(void){

   using namespace std;

    //capture data
   cout << "Enter the world's population: ";
   long worlds_pop; cin >> worlds_pop;
   cout << "Enter the u.s. population: ";
   long us_pop; cin >> us_pop;

   //operate on data
   long pop = us_pop/worlds_pop;
 
   //ouput results
   cout << "The United States population is ";
   cout << pop << " % of the worlds population.";
   cout << endl;
   return 0;
}

edit: yeah, it's obviously not std::cout, but I'm thinking its the way I'm operating on long?

You need to factor some float or double into the expression. You can do it by, for example

(us_pop * 1.0)/worlds_pop

or by casting the type of one variable

us_pop/static_cast<double>(worlds_pop)

The result will be a double, of course, so you have to cast it back to a long if you want to truncate it.
