Question

当我使用while循环时，vscode将无法运行我的代码... 平台：Windows 10 编译器：Visual Studio代码和Powershell核心语言：C ++

不使用while循环，它可以工作，但是我需要while循环才能再次运行程序。

#include <iostream>
#include <cmath>
#include <string>

using namespace std;

int main(){

    int replay = 0;
    int input;

    while(input == replay)
    {
        //Creating variables to store
        string celebrity = "Keeves Reeves";
        string guess;

        //Prompt the user
        cout << "Guess this celebrity: He acted as John Wick" << endl;
        getline(cin, guess);


        //Check the answer by using switch statement

        if(guess == celebrity){
            cout << "Congratulations! You are right" << endl;
            input = 3;
        } else if(guess != celebrity)
            cout << "Whoops, that not the right answer..." << endl;
            cout << "If you want to try again, enter '0' to replay, enter '1' to view the answer: ";
            cin >> input;
            if(input = 1){
                cout << "The celebrity was " << celebrity << " ." << endl;
            }
    }

    //Break from while loop
    cout << "Thank you for playing. The end." << endl;
    system("pause");

    return 0; } ```

D:\Programming Files\C++\vscode>cd "d:\Programming Files\C++\vscode\" && g++ Guess The Celebrity2.cpp -o Guess The Celebrity2 && "d:\Programming Files\C++\vscode\"Guess The Celebrity2
g++: error: Guess: No such file or directory

g++: error: Celebrity2.cpp: No such file or directory
g++: error: The: No such file or directory

compilation terminated.

****NOTE THAT: DO NOT BE LIKE ME, THIS ERROR OCCURS ONLY BECAUSE I PUT SPACE ON MY FILE NAME!!! HOPE THIS HELPS!!!

您必须对应用程序进行调用，并将调用编译为引号。完全与您的代码无关：

g++ "Guess The Celebrity2.cpp" -o "Guess The Celebrity2" && "d:\Programming Files\C++\vscode\Guess The Celebrity2"

此代码中有几个错误：

#include <iostream>
#include <cmath>
#include <string>

using namespace std;

int main(){

    int replay = 0;
    int input;

    while(int input >= replay)
    {
        //Creating variables to store
        string celebrity = "Keeves Reeves";
        string guess;

        //Prompt the user
        cout << "Guess this celebrity: He acted as John Wick" << endl;
        getline(cin, guess);


        //Check the answer by using switch statement
        if(guess == celebrity){
            cout << "Congratulations! You are right" << endl;
            input = 3;
        } else if(guess != celebrity){
            cout << "Whoops, that not the right answer..." << endl;
            cout << "If you want to try again, enter '0' to replay, enter '1' to view the answer: ";
            cin >> input;

            if(input = 1){
                cout << "The celebrity was " << celebrity << " ." << endl;
            }
        }
    }

    //Break from while loop
    cout << "Thank you for playing. The end." << endl;
    system("pause");

    return 0;
}

第一个输入未初始化。其次，您声明一个变量，然后将其比较以重播（覆盖输入）。第三，在最后一个if语句中，将输入设置为1，即进行比较。

#include <iostream>
#include <cmath>
#include <string>

using namespace std;

int main(){

    int replay = 0;
    int input = 0;

    while(input == replay)
    {
        //Creating variables to store
        string celebrity = "Keeves Reeves";
        string guess;

        //Prompt the user
        cout << "Guess this celebrity: He acted as John Wick" << endl;
        cin.ignore(); 
        getline(cin, guess);


        //Check the answer by using switch statement
        if(guess == celebrity){
            cout << "Congratulations! You are right" << endl;
            input = 3;
        } else if(guess != celebrity){
            cout << "Whoops, that not the right answer..." << endl;
            cout << "If you want to try again, enter '0' to replay, enter '1' to view the answer: ";
            cin >> input;

            if(input == 1){
                cout << "The celebrity was " << celebrity << " ." << endl;
            }
        }
    }

    //Break from while loop
    cout << "Thank you for playing. The end." << endl;
    system("pause");

    return 0;
}
