c++ - 基本控制台打印程序

Question

#include <iostream>
using namespace std;

int Main ()
{
    cout << "---------------------------------------------------------------------------------/n";
    cout << "NAME: Justin Chiang/n";
    cout << "COMPUTER LANGUAGES: Python, Lua, C++/n";
    cout << "FAVORITE VIDEO GAME: Starcraft, Diablo/n";
    cout << "I'm taking this class for math undergrad requirement and because it is very useful." << endl;
    system("PAUSE");
    return 0;
}

输出：

1>------ Build started: Project: HW1, Configuration: Debug Win32 ------
1>  HW1.cpp

            skipped when looking for precompiled header use
1>          Add directive to 'StdAfx.h' or rebuild precompiled header

            "StdAfx.h"' to your source?

Answer 1

转到项目属性。单击 Configuration Properties/C/C++/Precompiled Header 并选择“Not Using Precompiled Headers”选项。确切的说明可能会根据您使用的 Visual Studio 版本而有所不同，但基本上您希望关闭预编译头文件。

Answer 2

你不见了#include "stdafx.h"

此外，int Main()不是标准 C++，你应该用int main()or替换你的 main 函数int main(int argc, char** argv)

既然我不得不说为什么你必须使用预编译的头文件，它可以使 MSVC 的编译时间更快，但它阻碍了可移植性，并且如果使用它会拖拽很多不符合标准的代码。它可能会破坏您的可移植性，但如果您正在使用另一个 IDE，您可以轻松地删除头文件。

Answer 3

int Main ()应该是小写。将其更改为int main ().

和

更改cout << "... /n"; 为cout << "... \n";

#include <iostream>
using namespace std;

int main ()
{
    cout << "---------------------------------------------------------------------------------\n";
    cout << "NAME: Justin Chiang\n";
    cout << "COMPUTER LANGUAGES: Python, Lua, C++\n";
    cout << "FAVORITE VIDEO GAME: Starcraft, Diablo\n";
    cout << "I'm taking this class for math undergrad requirement and because it is very useful." << endl;
    system("PAUSE");
    return 0;
}
