思路很清晰的c++课件。例子很简明

#include <iostream.h>
int mul(int a,int b)        //两个数的乘积
{
   return a*b;
}
______(1)______             //三个数的乘积
{
   return a*b*c;
}
______(2)______             //四个数的乘积
{
   return a*b*c*d;
}
void main()
{   int x1,x2,x3,x4;
    cin>>x1>>x2>>x3>>x4;
    cout<<"两个数的积："<<mul(x1,x2)<<endl;
    cout<<"三个数的积："<<mul(x1,x2,x3)<<endl;
    cout<<"四个数的积："<<mul(x1,x2,x3,x4)<<endl;
}
