main返回值必须为int,貌似已经是int了

#include<iostream>
using namespace std;

struct employee
{
    char name[20];
    int empNo;
    float salary;
    float hourlyPay;
    int workHours;
}
int main()
{
    int nums;
    cout<<"请输入员工的人数:";
    cin>>nums;
    struct employee *emp;
    emp=new employee[nums];
    for(int i=0;i<nums;i++)
    {
        cout<<"请输入第"<<i+1<<"个员工的姓名: ";
        cin>>emp[i].name;
        cout<<"请输入第"<<i+1<<"个员工本月的工作时数: ";
        cin>>emp[i].workHours;
        emp[i].empNo=1001+i;
        emp[i].hourlyPay=50.0;
        emp[i].salary=emp[i].hourlyPay*emp[i].workHours;
    }
    for(int i=0;i<nums;i++)
        cout<<emp[i].empNo<<"号员工"<<emp[i].name<<"的月薪为:"<<emp[i].salary<<"元。"<<endl;
   
    system("pause");
    return 0;
}
