Question

當我使用 while 循環時，vscode 將無法運行我的代碼... 平台：Windows 10 編譯器：Visual Studio 代碼和 Powershell 核心語言：C++

不使用while循環，然后它可以工作，但我需要while循環來再次運行我的程序。

#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

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

Answer 1

您必須調用應用程序並將調用編譯為引號。 它與您的代碼完全無關：

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

這段代碼有幾個錯誤：

#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;
}

第一個輸入未初始化。 其次，您聲明一個變量，然后將其與重播進行比較（您覆蓋輸入）。 第三，在最后一個 if 語句中，您將 input 設置為 1，而不是比較它。

#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;
}
