        N=1461*n1/4+153*n2/5+n3;
        return N;
    }
};
这个是我建好的类
然后在另一个工程里面调用这个类创造对象和调用方法
#include<iostream>
#include<minu.h>
void apply()
{
    minu date1;
    minu date2;
}
int sub(int a,int b)
{
    return (a-b);
}
void loop()
{
    cout<<"ÊäÈë(Y)¼ÌÐø²âÑé»òÕßÊäÈë(N)½áÊø³ÌÐò";
    int decision;
    cin>>decision;
    switch(toupper(decision))
    {
        case 'Y':
            {
                apply();
                date1.readIn();
                date2.readIn();
                int sub;
                sub=sub(date1.methodN-date2.methodN);
                cout<<date1.getYear()<<" "<<date1.getMonth()<<" "<<date1.getDay()<<" "<<"Óë"<<date2.getYear()<<" "<<date2.getMonth()<<" "<<
                        date2.getDay()<<"Ïà²î"<<sub<<"Ìì"<<endl;
            }
        case 'N':
            {
                cout<<"³ÌÐò½áÊø"<<endl;
            }

int main(void)
{
    apply();
    date1.readIn();
    date2.readIn();
    int sub;
    sub=sub(date1.methodN-date2.methodN);
    cout<<date1.getYear()<<" "<<date1.getMonth()<<" "<<date1.getDay()<<" "<<"Óë"<<date2.getYear()<<" "<<date2.getMonth()<<" "<<
        date2.getDay()<<"Ïà²î"<<sub<<"Ìì"<<endl;
    loop();
    system(pause);
    return 0;
}
但是老实说找不到上面的那个类...

这个minu是自己建立的类文件.
调用时应为#include"minu.h".
你试试吧。

#include<minu.h>改成＃include"minu.h"

void apply()
{
    minu date1;
    minu date2;
}
不知道你这个要做什么的

sub=sub(date1.methodN-date2.methodN);
你在类中定义是
int methodN(int n1,int n2, int n3)
        N=1461*n1/4+153*n2/5+n3;
        return N;
    }
这样调用肯定是错的
