Question

C++入门，不懂啊，找不到错，哥哥姐姐们帮帮忙

#include "stdafx.h"
#include "iostream"
using namespace std;

int main()
{

int day,month,num;
int hour,mint,sec;
printf("Hello World!\n");
cout<<"请输入一个任意整数: ";
cin>>num;
sec = getsec(num);
cout<<12<<"年"<<12<<"月"<<12<<"日"<<12<<":"<<12<<":"<<sec<<","<<"friday" <<endl;
}

int getsec(int num){

int s=num%60;
return s;
}

Answer 1

#include <iostream> // 这里不用包含stdafx.h
using namespace std;
int getsec(int); //这是你的自定义函数，在你使用它之前应该先定义其函数原型，或者把你的函数
int main()//定义放在main（）之前！楼上在main()中定义函数原型不是很推荐
{
int day,month,num;
int hour,mint,sec;
printf("Hello World!\n");
cout<<"请输入一个任意整数: ";
cin>>num;
sec = getsec(num);
cout<<12<<"年"<<12<<"月"<<12<<"日"<<12<<":"<<12<<":"<<sec<<","<<"friday" <<endl;
return 0;//return 0语句，虽然这里不添加该语句不会影响程序运行结果，
}//但是编译器可能会给出警告。你使用的是int main()，如果使用void main（）就不用加！
int getsec(int num)
{
int s=num%60;
return s;
}

Answer 2

修改后的代码：
#include "iostream"
using namespace std;

int main()
{

int day,month,num;
int hour,mint,sec;
printf("Hello World!\n");
cout<<"请输入一个任意整数: ";
cin>>num;
int getsec(int num);
sec = getsec(num);
cout<<12<<"年"<<12<<"月"<<12<<"日"<<12<<":"<<12<<":"<<sec<<","<<"friday" <<endl;
}

int getsec(int num){

int s=num%60;
return s;
}

追问

和以前一样，还是一个错误
Compiling...
work_11_09_13.cpp
c:\users\move\documents\project\work_11_09_13\work_11_09_13.cpp(51) : fatal error C1010: unexpected end of file while looking for precompiled header directive
Error executing cl.exe.

work_11_09_13.obj - 1 error(s), 0 warning(s)

Answer 3

用的VC6.0吗，不支持标准c++的，#include "iostream"改成#include "iostream.h"

追问

该成#include "iostream.h" 没用改成现在的这个的，这个有用

Answer 4

#include "stdafx.h"
#include <iostream.h>
int main()
{

int day,month,num;
int hour,mint,sec;
printf("Hello World!\n");
cout<<"请输入一个任意整数: ";
cin>>num;
sec = getsec(num);
cout<<12<<"年"<<12<<"月"<<12<<"日"<<12<<":"<<12<<":"<<sec<<","<<"friday" <<endl;
return 0;
}

int getsec(int num){

int s=num%60;
return s;
}
