C++ C++；猜谜游戏 #包括 #包括 #包括 使用名称空间std； int main（）； 无效菜单（）； 无效游戏（）； 再次无效（）； int main（） { //为随机数生成器设定种子 srand（时间（0））； 菜单（）； 返回0； } //菜单，以便继续播放或关闭程序 无效菜单（） { 整数选择=0； 布尔播放=真； 玩的时候 { 我可以看到多个问题： 游戏结束时，您缺少结尾“}”，再次出现函数 在后一种情况下，返回是可选的，并且应该在末尾有一个“；” 您正在将“decision”与单位化变量y、y、n和n进行比较……我猜您希望将其值与字符“y”、“y”、“n”、“n”进行比较 “else if（decision！=y，y | | n，n）”不是有效的语法，在这种情况下，您已经只使用了一个“else” 在“再次作废（）”的末尾有一个额外的“；” 您正在尝试使用“void PlayGame（）；”调用函数 程序所采用的路径不干净，并且您正在执行不需要的递归，最好返回一个值

我会这样做：

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main();
void Menu();
void PlayGame();
void Again();

int main()
{
// Seed the random number generator
srand(time(0));
Menu();
return 0;
}

// Menu so can keep playing or close the program
void Menu()
{
int selection = 0;
bool playing = true;

while (playing)
{
    cout << "Guess Number Game\n\n";
    cout << "Menu\n\n";
    cout << "1) Play Game\n";
    cout << "2) Exit\n\n";
    cout << "Enter your selection: ";
    cin >> selection;
    cin.ignore();
    cout << endl;

    if (selection == 1)
       PlayGame();
    else if (selection == 2)
        playing = false;
    else if (selection != 1 || 2) //lets the user know why they are going        back to the menu
        cout << "Try again, choose 1 or 2" << endl;
  }

}

    attempts--;

    if (attempts == 0)
    {

cout首先，您应该解决Alde提到的问题。接下来是
while（true）
语句的问题？您可能应该将其替换为
while（truments！=0）
，并设置：

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;


void PlayGame()
{
    const int HighestNum = 50;
    const int LowestNum = 1;

        --attempts;
    }

    cout << "Sorry, no guesses remain. The random number was... " << RandomNumber << "!\n\n";
}

bool Menu()
{
    cout << "Guess Number Game\n\n";

    cout << "Menu\n\n";

    cout << "1) Play Game\n";

        else
            cout << "Try again, choose 1 or 2: ";

谢谢，再次使用菜单设置播放会更有意义。我不确定是否可以在void中调用void函数。我刚刚开始学习各种类型的函数。再次感谢。谢谢。我需要int reviewGuess（int，int）若要获取返回值，请包含一个switch语句以给出每个值的响应。基本上，返回值0必须=“You win！！”1“您的选择高于randomNumber”-1“您的选择低于randomNumber”但是在集成int-reviewGuess（int-randomNumber，int-userChoice）{int x如果（randomNumber==userChoice）x=0；如果（randomNumber>userChoice）x=1；如果（randomNumberint reviewGuess(int randomNumber,int userChoice)
{
    if(randomNumber == userChoice)
       return 0;
    if(userChoice > 50)
       return 1;
    if(userChoice < 1)
       return -1;
}
