清除控制台以模拟菜单C

找到了我写的基于文本的岩石剪刀应用后，我决定改进代码。现在，我想在返回主菜单之前和执行请求的应用程序操作之前写入控制台以清除屏幕。这是代码：

#include <iostream>
#include <string>
#include <cstdlib>
#include <time.h>
#include <algorithm>
using namespace std;
void scoreCounter(int playerWins, int playerTies, int playerLosses, int compWins, int compTies, int compLosses)
{
    cout << "PLAYER SCORE:nn";
    cout << "Wins: " << playerWins << "n";
    cout << "Losses: " << playerLosses << "n";
    cout << "Ties: " << playerTies << "nnn";
    cout << "COMPUTER SCORE:nn";
    cout << "Wins: " << compWins << "n";
    cout << "Losses: " << compLosses << "n";
    cout << "Ties: " << compTies << "nnn"; 
}
void mainMenu()
{
    cout << "Main Menunn";
    cout << "1) Play Rock Paper Scissorsn";
    cout << "2) Display scoreboardn";
    cout << "3) Exit appn";
    cout << "n";
}
void rockPaperScissorsShoot(int playerWins, int playerTies, int playerLosses, int compWins, int compTies, int compLosses) {
    cout << "Rock Paper Scissors Shoot!n";
    string playerChoice;
    cin >> playerChoice;
    transform(playerChoice.begin(), playerChoice.end(), playerChoice.begin(), ::tolower);
    int n1;
    int n2;
    int n3;
    srand(time(NULL));
        if (playerChoice == "Rock" || playerChoice == "rock") {
            n1 = rand() %3;
            if (n1 == 0) {
                cout << "You win!n";
                playerWins++;
                compLosses++;
            }
            else if (n1 == 1) {
                cout << "You lose!n";
                playerLosses++;
                compWins++;
            }
            else if (n1 == 2) {
                cout << "You tied!n";
                playerTies++;
                compTies++;
            }
        }
        else if (playerChoice == "Paper" || playerChoice == "paper") {
            n2 = rand() %3;
            if (n2 == 0) {
                cout << "You win!n";
                playerWins++;
                compLosses++;
            }
            else if (n2 == 1) {
                cout << "You lose!n";
                playerLosses++;
                compWins++;
            }
            else if (n2 == 2) {
                cout << "You tied!n";
                playerTies++;
                compTies++;
            }
        }
        else if (playerChoice == "Scissors" || playerChoice == "scissors") {
            n3 = rand() %3;
            if (n3 == 0) {
                cout << "You win!n";
                playerWins++;
                compLosses++;
            }
            else if (n3 == 1) {
                cout << "You lose!n";
                playerLosses++;
                compWins++;
            }
            else if (n3 == 2) {
                cout << "You tied!n";
                playerTies++;
                compTies++;
            }
        }
        else {
            cout << "You made an invalid choice. Ending game...n";
        }
    }
int main()
{
    bool gameOver = 0;
    bool exitProg = 0;
    int playerWins = 0;
    int playerTies = 0;
    int playerLosses = 0;
    int compWins = 0;
    int compTies = 0;
    int compLosses = 0;
    int menuChoice;
    while (exitProg != 1)
    {
        mainMenu();
        cin >> menuChoice;
        switch (menuChoice)
        {
            case 1:
            {
                while (gameOver == 0) {
                    rockPaperScissorsShoot(playerWins, playerTies, playerLosses, compWins, compTies, compLosses);
                    cout << "Would you like to play again? Press Y or N:n";
                    char yOrN;
                    cin >> yOrN;
                    switch (yOrN) {
                        case 'Y': {
                            cout << "Ok then!n";
                            break;
                            }
                        case 'y': {
                            cout << "Ok then!n";
                            break;
                            }
                        case 'N': {
                            cout << "Game over.n";
                            gameOver = 1;
                            break;
                        }
                        case 'n': {
                            cout << "Game over.n";
                            gameOver = 1;
                            break;
                        }
                    }
                }
                cout << "n";
                break;
            }
            case 2:
            {
                scoreCounter(playerWins, playerTies, playerLosses, compWins, compTies, compLosses);
                break;
            }
            case 3:
            {
                exitProg = 1;
                system("PAUSE");
                break;
            }
        }
    }
    return 0;
}

我考虑使用cin.clear()，但是如果我想打开其他功能，我认为这对我没有帮助。我该怎么办？
