Thread: whats wrong with this program please?

Code:

#include <iostream.h>
#include <windows.h>

int main()
{
	const double met=35273.92;
	double mt;
	double oz;
	double boxes;
	char go;
	int i=0;
	for(;;)
	{
		system("CLS");
	    cout<<"Enter the number of ounces in your breakfast cereal: ";
	    cin>>oz;
	    mt=oz/met;
		for(i;i<=met;i+=oz)
		{
			if(i>met) i-=oz;
		}
		if(met-i>0) boxes++;
		//if(met%oz>0) boxes++; this does not work for some reason
	    cout<<endl<<"Your cereal is "<<mt<<" metric ton(s) and it would take "<<boxes<<" boxes to make a metric ton."<<endl<<endl;
		cout<<"Would you like to do another cereal?(y/n): ";
		cin>>go;
		if(go=='n' || go=='N') break;
	}
	return 0;
}
