C++ 基于函数的字母猜测游戏

我正在尝试为一个类项目做一个基于函数的字母猜测游戏。我以前完成了一个程序，将产生一个随机字母，现在我需要使其功能的基础上，但它不工作。任何帮助都将不胜感激

#include<iostream> 
#include<cstdlib>
#include<ctime> 
using namespace std;

void introduction();
//Display the introduction

int getNumberOfGames(int& number_of_games);
//Ask individual how many games they want to play
//

char compareTwoCharacters(char answer, char& guess);
//

char playOneGame(char answer);
//function returns true if user won;otherwise will return false. going to call the 3rd function to decide if correct or not



int main()
{
char alphabet [27];
int number_of_games;
char guess;
int games = 1;
char n = (char)(rand() % 26 + 1);
srand(time(0));


void introduction();
int getNumberOfGames(int);
char compareTwoCharacters(char,char);
char playOneGame(char);

    system("pause");

}

void introduction()
{
    cout<<"Weclome to the Letter Guessing game!\n";
    cout<<"You have 5 chances to guess each letter.\n \n";
    cout<<"Let's begin!\n";
    cout<<"**************************************************\n\n";

}

int getNumberOfGames(int& number_of_games)
{
    cout<<"How many games do you want to play? \n";
    cin >> number_of_games;
    return 0;

}

char compareTwoCharacters(char answer, char guess)
{
    cout << "Enter your guess: ";
    cin >> guess;
    if (guess == answer)
        return 0;
    else if (guess < answer)
        return 2;
    else
        return -2;
}

char playOneGame(char answer)
{
    //return true is guess = answer otherwise return false
    return true;

    while (games <= number_of_games) 
    char answer = 97 + rand() % 27;
    cout << "Lets play game " << games++ << '\n';
    for (int number_of_guesses = 0; number_of_guesses < 5; number_of_guesses++)
    {

        cout << "Enter your guess: ";
        cin >> guess;
        if (guess > answer)
        {
            cout << "The letter you are trying to guess is before " << guess << "\n";

        }
        else if (guess < answer)
        {
            cout << "The letter you are trying to guess is after " << guess << "\n";

        }
        else
        {
            cout << "Your guess is correct! \n";

            break;
        }

}
    cout << "The answer you were looking for was " << answer << '\n';
    return 0;
}

cout代码中存在大量语法错误：

首先，
srand（time（NULL））
函数应该出现在生成随机数之前，而不是之后。因此，您应该移动它，使代码看起来像：

srand(time(NULL));
// Add the rest of your code here
char n = (char)(rand() % 26 + 1);

其次，函数
playOneGame（）中的while循环
：

while（games正如许多人已经说过的，您的代码中有很多语法错误

首先，在使用
rand（）
函数之前，应该为随机值生成器设置种子（使用
srand（）
）。因此，
srand（时间（0））
应该在
charn=（char）（rand（）%26+1）；
之前，而不是之后

Second调用函数时，不需要添加返回类型。例如，在
main（）
函数中，函数
void introduction（）；
应更改为
introduction（）；
，与接下来的3个函数调用相同（请参阅：）

Third调用函数时，您需要一个参数，而不是类型。例如，您的函数调用
compareTwoCharacters（char，char）；
不应将
char
作为其参数，而应具有如下变量或文字：
compareTwoCharacters（n，'a'））；
。在编写的3个函数调用中进行这些更改

Forth，在
字符比较字符（字符回答，字符猜测）
（第57行）函数，您应该返回一个
char
，但在代码中，您返回了一个整数：
return 0；
和
return 2；
和
return-2；
。确保返回语句和返回类型匹配。这与
char playOneGame（char-answer）中的问题相同
函数；返回的是
true
，但返回类型是
char

Fifth，在您的
char playOneGame（char-answer）
函数中，您缺少while循环的括号。如果没有括号，它将只循环下一个命令，即
char-answer=97+rand（）%27；
和永不结束（无限循环），因为从未达到退出条件

Sixth，在同一函数中，变量
game
从未声明。它是在不同的函数中声明的（
int games=1；
，在第26行），但一旦退出该函数，
game
将停止退出（有关详细信息：）

我修复了一些错误，试图保持代码的一般结构不变，并用
//CHANGED
