【问题描述】:
我正在用 C 语言创建刽子手,但有一个问题我不能完全掌握。当用户正确猜出被猜词所具有的字母之一时,程序会将之前猜到的所有字母替换给刚刚输入的那个用户。这个问题的根源是什么?
#include<stdio.h>
#include <stdlib.h>
int main()
{
srand(time(NULL));
int x = 0, isCompleted, matchFound, numberOfTries = 7;
char letterGuess[1];
int randomIndex = rand()%14;
const char *wordArray[14];
const char *guessedWord[10];
const char *usedLetters[17];
for (int k = 0; k < 10; k++) {
guessedWord[k] = "_";
}
wordArray[0] = "butonierka";
wordArray[1] = "centyfolia";
wordArray[2] = "chiroplast";
wordArray[3] = "cmentarzyk";
wordArray[4] = "chrustniak";
wordArray[5] = "budowniczy";
wordArray[6] = "cholewkarz";
wordArray[7] = "cornflakes";
wordArray[8] = "brzydactwo";
wordArray[9] = "germanofil";
wordArray[10] = "lichtarzyk";
wordArray[11] = "lutowniczy";
wordArray[12] = "mikrocysta";
wordArray[13] = "tryskawiec";
const char *wordToGuess = wordArray[randomIndex];
for(int i = 0; i < 10; i++) {
printf(" %s ", guessedWord[i]);
}
printf("\n");
while(numberOfTries != 0 && isCompleted != 10) {
matchFound = 0;
isCompleted = 0;
printf("Please give a lowercase letter\n");
printf("Left tries: %d\n", numberOfTries);
scanf("%s", &letterGuess);
for (int z = 0; z < 17; z++) {
if (usedLetters[z] == letterGuess[0]) {
matchFound = 1;
}
}
if (letterGuess[0] >= 'a' && letterGuess[0] <= 'z' && matchFound == 0) {
usedLetters[x] = letterGuess[0];
x++;
for (int j = 0; j < 10; j++) {
if (letterGuess[0] == wordArray[randomIndex][j])
guessedWord[j] = letterGuess;
matchFound = 1;
}
}
if (matchFound == 0) {
numberOfTries--;
}
for(int z = 0; z < 10; z++) {
printf(" %s ", guessedWord[z]);
}
printf("\n");
} else {
if (matchFound == 1) {
printf("You've already given such letter!!\n");
} else {
printf("Wrong input, please try again!\n");
}
}
for (int k = 0; k < 10; k++) {
if (guessedWord[k] != "_") {
isCompleted++;
}
}
if (isCompleted == 10) {
printf("You have correctly guessed a word! Congrats!!\n");
}
printf("\n\n");
}
printf("The word was: %s\n", wordArray[randomIndex]);
printf("Game over!!\n");
}

欢迎来到 Stack Overflow! 寻求调试帮助的问题(为什么这段代码不起作用?)必须包括所需的行为、特定的问题或错误以及在问题本身中重现它所需的最短代码。没有明确问题陈述的问题对其他读者没有用处。请参阅:如何创建minimal reproducible example。
-
注意:
isCompleted未初始化。第一次迭代时可能是 10。 -
您的代码无法编译。请提供minimal reproducible example。
-
第一个while循环之前呢?
-
你的程序太复杂了,你应该从头开始重新考虑清楚的算法,你有太多的循环,太多的变量......使用函数!修改你的概念。
