在C ++方面，我是一个业余爱好者，我很乐意看到我可以做些什么来改进我编写的帮助我完成AP英语功课的程序。基本上，它会打印单词的定义，您必须正确匹配它们。如果错误，则显示“错误，正确的单词是：（正确的单词）”；如果正确，则显示“ Great！”。
所以我也有一些关于为什么东西起作用的问题，我正在编码并且就像wtf一样不应该起作用，但是确实可以
（代码下方的问题）
#include <iostream>
#include <string>
#include <ctime>

using namespace std;
class APMC {

int main() {
// Is the game running?
bool isGameRunning = true;
// Casts an integer to time and stores it into random so it is for SURE random!
srand((int)time(0));
// Classes object key thing
APMC words;
// The whole program is ran in a loop, declared above
while (isGameRunning) {
// Random between 0 and 56 because there is 56 words
int random = (rand() % 56) + 0;
string userInput;
// Displays a random definition
cout << "The definition is: " << words.description[random] << endl;
cin >> userInput;
system("cls");
// This is where im confused on WHY this worked
if (userInput == words.word[random]) {
cout << "Great!" << endl;
}
else {
// Also confused on why this worked, but displays the correct answer if it is wrong
cout << "Wrong, the answer was: " << words.word[random] << endl;
}
}
return 0;
}
问题：
1.说的部分
"if (userInput == words.word[random]) {
cout << "Great!" << endl;
}"
好吧，为什么这行得通？这是偶然的，基本上说如果userInput是一个字符串，则按字符串等于数组中的单词，则匹配。但是，数组不是按数字分类的吗。0-56？那么数组如何知道userInput，它采用字符串值，与数组中的INTEGER值匹配？
它说的部分感到困惑
“ cout <<”错误，答案是：“ << << words.word [random] << endl;”
好吧，它是一个随机数吧？它怎么会记得显示时是什么单词？我肯定认为这将显示一个不同的词。我的猜测是，当它循环并在开始时声明随机部分时，它将组成新的数字。
谢谢大家，对不起，如果我措辞如此。
寻找改进！
