【问题描述】:
我正在用 C++ 制作一个刽子手游戏,我即将完成,但是我有一个主要问题。我必须让游戏只允许用户 4 次猜测,但我的程序没有记录正确的猜测次数。
我尝试更改变量以及 if 和 else 语句中关于猜测的条件。
#include <iostream>
#include <string>
#include <vector>
using namespace std;
int main() {
cout << "Welcome to hangman!" << endl;
char choice = 'y';
while (choice == 'y') {
string word;
cout << "Enter a word to guess: ";
getline(cin, word);
if (word.empty()) {
cout << "The word should not be blank.\n";
continue;
}
bool contain_space = false;
for (char c : word) {
if (isspace(c)) {
contain_space = true;
break;
}
}
if (contain_space) {
cout << "The word cannot contain spaces.\n";
continue;
}
vector <bool> index;
for (int i = 0; i < word.size(); i++) {
index.push_back(false);
}
**int guess_correct = 0;**
int guess_wrong = 4;
char letter;
while (guess_wrong >= 0 && guess_correct < word.size()) {
bool valid_guess = true;
cout << "Guess a letter." << endl;
cin >> letter;
for (int i = 0;i < word.size(); i++) {
if (word[i] == letter) {
valid_guess = true;
index[i] = true;
guess_correct++;
break;
}
else {
guess_wrong = guess_wrong - 1;
}
}
for (int i = 0; i < word.size(); i++) {
if (index[i] == true) {
cout << word[i] << "\t";
}
else {
cout << "___\t";
}
}
cout << endl;
}
cout << "Would you like to play again? (y/n)" << endl;
cin >> choice;
cin.ignore();
}
return 0;
}
黑色勾号显示我卡住的代码部分的开头。每次我运行它,它都会让我以正确的猜测完成游戏,但错误的猜测不允许 4。
【问题讨论】:
-
bool valid_guess = true;您可能希望将其初始化为 false 。如果在你的for (int i = 0;i < word.size(); i++) { }之后它仍然是错误的,那么只有这样才能减少guess_wrong
