Visual Studio 中的致命错误 C1010 -“stdafx.h”如何纠正？

Question

我编译了以下代码，但在 Visual Studio 中出现了我无法理解的编译错误。

#include <iostream>

using namespace std;

int main()
{
    int matchCount, findResult;
    long childPID;
    string userInput = "blank";

    // string to be searched through
    string longString = "The PPSh-41 is a Soviet submachine gun designed by Georgi Shpagin as an inexpensive, simplified alternative to the PPD-40.";

    while (userInput.compare("!wq"));
    {
        // reset variables for reuse
        matchCount = 0;
        findResult = -1;

        cout << "Please enter a word/s to search for (!wq to exit): "; // prompts user for string to search for
        cin >> userInput; // takes user input
        
        if (userInput.compare("!wq")) // checks user input to see if they still wish to search for a string
        {
            childPID = fork();

            if (childPID == 0)
            {
                while (findResult < longString.length)
                {
                    findResult = longString.find(userInput, findResult + 1, userInput.length);
                    
                    if (findResult < longString.length)
                        matchCount++;
                }

                cout << "There are " << matchCount << " instances of " << userInput << " in longString." << endl;
            }
            else
                cout << "childPID != 0" << endl;
        }
        else
            cout << "User has chosen to exit. Exiting." << endl;
    }

    return 0;
}

错误内容为：

“wordcount.cpp(57)：致命错误 C1010：查找预编译头时文件意外结束。您是否忘记将 '#include "stdafx.h"' 添加到源中？"

我不认为我需要头文件来运行此代码。

Answer 1

看看https://stackoverflow.com/a/4726838/2963099

关闭预编译头：

Project Properties -> C++ -> Precompiled Headers

将

Precompiled Header

设置为

"Not Using Precompiled Header"

。

Answer 2

项目的每个源文件的第一行必须如下：

#include <stdafx.h>

访问这里了解预编译头文件

Answer 3

创建一个新的“空项目”，将您的Cpp文件添加到新项目中，删除包含stdafx的行。

完成。

该项目不再需要stdafx。当您使用已安装的模板创建项目时，它会自动添加。
