Question

我正在制作一个记忆游戏（到目前为止还不顺利）并且我遇到了这个问题，我的随机函数或我在new_game函数中的循环似乎是乱七八糟的。我是c ++的初学者，所以任何帮助都会非常感激。我知道代码有点无组织和笨拙，更不用说没有优化。新的一切。

#include <iostream.h>
#include <stdio.h>
#include <string.h>
#include <fstream.h>
#include <conio.h>
#include <ctype.h>

void main_menu();
////////////NECESSARY VARIABLES////////////
int score=0;
int highscore;

//////////NECESSARY FILE HANDLERS//////////
fstream filehandlerHS;
//^^^HIGH SCORE STATS^^^//

//////////FUNCTION TO CREATE RANDOM STRING//////////

char vocab[]={0,1,2,3,4,5,6,7,8,9};////POSSIBLE CHARACTERS

char random()
{
    return vocab[rand() %10];
}

///////////////NEW GAME/////////////
void New_Game()
{
    cout<<"......Welcome To The Memory Game!.......";
    cout<<"A series of random characters will be shown to you\n"
        <<"For a specific period of time, you have to remember it\n"
        <<"And once the text dissapears, enter it, correct answers gives 5        points\n"
        <<"Wrong answer means game over! ready? \n";
    system("Pause");
    system("cls");
    for(int i=0; i<10;i++)
    {
        char entry[9];
        char term[9];
        for(int j=0; j<i;j++)

问题在于

cout << term;

没有做你认为的事情。由于term被声明为char的数组，因此它认为它是C风格的字符串，而不是数字数组。因此，它将数组的内容视为字符代码，并期望它以空字节结束。由于数字0到9是控制字符，因此您会收到垃圾。

首先，vocab应包含您要显示的字符，而不是数字：

char vocab[]={'0','1','2','3','4','5','6','7','8','9'};////POSSIBLE CHARACTERS

或更简单：

char vocab[] = "0123456789";

然后，您应该使用std::string而不是char数组。

std::string entry;
std::string term;
for (var j = 0; j < i; j++) {
    term.push_back(random());
}
cin >> entry;
if (entry == term) {
    ...
}

您也无法将数组与==进行比较。如果要判断两个数组是否包含相同的值，则需要循环遍历它们，逐个元素地比较它们。但是，std::string和term使用entry也可以解决这个问题。

输出我的char数组范围，同时使用rand（）
