函数运行正常，却没法return0是为什么

Question

最近学到类，用类写一个计算工资的题目，题目写完了，但总是在运行结束后要等一段时间，然后返回值不是0而是一串很长的数，求大佬解惑

#include <iostream>
#include<cstdlib>
#include"payroll.h"
using namespace std;
int main()
{
int rate,hour,counts=0;
payroll*p=new payroll[7];
payroll*s=p;
for(counts=0;counts<7;counts++,p++)
    {
        cout<<"enter the hourly pay rate of employee "<<counts+1<<":";
        cin>>rate;
        cout<<"enter the working hour of employee "<<counts+1<<":";
        cin>>hour;
        if (hour < 0)
            {
                cout <<"NO NEGATIVE HOURS ARE ALLOWED\n ";
                counts--;
            }
            if (hour> 60)
            {
                cout <<"Valid hours are from 0 - 60\n ";
                counts--;
            }
           (*p).Sethour(hour);
           p->Setrate(rate);

    }
    for(counts=0;counts<7;counts++,s++)
        {cout<<"The gross of employee "<<counts+1<<"is: "<<s->gross()<<endl;}


        delete []p;
        p=NULL;

    return 0;
}

我的destructor里有设置cout<<"success!";可是并没有显示，是不是说明没有成功地删除

Answer 1

delete s；删掉

p是new申请的空间，delete[]p;释放掉了，再delete s就出错了。

p++; p已经发生变化了，必须恢复最初值才能delete

    p=s;//增加
    for(counts=0;counts<7;counts++,s++)
    {cout<<"The gross of employee "<<counts+1<<"is: "<<s->gross()<<endl;}


    delete []p;
    p=NULL;

    return 0;
