Thread: argh.... why is the percent field always 0.00?

Code:

#include <iostream.h>

int main()

{
	int Awbrey1;
	int Awbrey2;
	int Awbrey3;
	
	int Berlin1;
	int Berlin2;
	int Berlin3;

	cout<<"Number of votes for Awbrey in New York: ";
	cin>>Awbrey1;
	cout<<"Number of votes for Berlin in New York: ";
	cin>>Berlin1;
	cout<<"Number of votes for Awbrey in New Jersey: ";
	cin>>Awbrey2;
	cout<<"Number of votes for Berlin in New Jersey: ";
	cin>>Berlin2;
	cout<<"Number of votes for Awbrey in Connecticut: ";
	cin>>Awbrey3;
	cout<<"Number of votes for Berlin in Connecticut: ";
	cin>>Berlin3;
	
	long awbreytotal=(Awbrey1+Awbrey2+Awbrey3);
	long berlintotal=(Berlin1+Berlin2+Berlin3);
	long total=(awbreytotal+berlintotal);
	double awbreypercent=double(((Awbrey1+Awbrey2+Awbrey3)/total)*100);
	double berlinpercent=double(((Berlin1+Berlin2+Berlin3)/total)*100);

	cout<<endl;
	const int ColWidth=15;
	cout.setf(ios::fixed);
	cout.precision(2);

	cout.setf(ios::left);
	cout.width(ColWidth); cout<<"Name";
	cout.setf(ios::right);
	cout.width(ColWidth); cout<<"Votes";
	cout.width(ColWidth); cout<<"Percent"<<endl;
	
	cout.setf(ios::left);
	cout.width(ColWidth); cout<<"Awbrey";
	cout.setf(ios::right);
	cout.width(ColWidth); cout<<awbreytotal;
	cout.width(ColWidth); cout<<awbreypercent<<endl;
	
	cout.setf(ios::left);
	cout.width(ColWidth); cout<<"Berlin";
	cout.setf(ios::right);
	cout.width(ColWidth); cout<<berlintotal;
	cout.width(ColWidth); cout<<berlinpercent<<endl;
	
	cout.setf(ios::left);
	cout.width(ColWidth); cout<<"TOTAL VOTES";
	cout.setf(ios::right);
	cout.width(ColWidth); cout<<total<<endl;
	return (0);
}

see the topic :9

Change the lines that calculate the percent to

double awbreypercent=((((double)Awbrey1+Awbrey2+Awbrey3)/total)*100);
double berlinpercent=((((double)Berlin1+Berlin2+Berlin3)/total)*100);

otherwise you're just doing integer division (which will have already been evaluated by the time you cast to double).
