Question

When I am using while loop, vscode will be unable to run my code... Platform: Windows 10 Compiler: Visual Studio Code and Powershell Core Language: C++

Not using while loop, then it works, but I need while loop to run my program again.

#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

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

You have to put your call of the application and compile calls in quotes. It has nothing to do with your code at all:

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

There are several errors in this code:

#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;
}

First input isn't initialized. Second you declare a variable and then compare it to replay (you overwrite input). Third, in your last if statement, you set input to 1, isntaead of comparing it.

#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;
}
