思路很清晰的c++课件。例子很简明

#include <iostream.h>
_______(1)_______             //求int型数据之差
{
   return x-y;
}
_______(2)_______             //求float型数据之差
{
   return x-y;
}
double Sub(double x,double y) //求double型数据之差
{
   return x-y;
}
void main()
{
    cout<<"5-3="<<Sub(5,3)<<endl;
    cout<<"5.2-3.5="<<Sub(5.2f,3.5f)<<endl;
    cout<<"8.6-7.1="<<Sub(8.6,7.1)<<endl;
}
