int or double??

[espionage1]

Why double: int linemen_weight = 0; int other_weight = 0; int total_weight = 0; ...

Instead of what I have int? (yes this is a broken code, I don't want classmates copying my code).

#include <iostream>	
using namespace std;

int main()	{
   			int k = 20;	
   			int player_number;
			int weight;
		  	int backs = 0;	
  			int linemen = 0;
  			int other = 0; 
  			int backs_weight = 0; 
  			int linemen_weight = 0;
  			int other_weight = 0;
  			int total_weight = 0;
    
while (k > 0) // Begins the loop.
{
datain >> player_number >> weight;
if (player_number >=1 && player_number <=49)	
{
backs ++ ;
backs_weight += weight;
}
else if (player_number >=50 && player_number <=79)	
{
linemen ++ ;
linemen_weight += weight;
}
else 
{
other ++ ;	
other_weight += weight;
}
total_weight += weight;
k--; // Should stop the loop.
}

}

With double you will have a more accurate number.

double: 1 / 2 = 0.5
int: 1 / 2 = 0

If you have no division and the accuracy isn't required you can of course use int.
