为什么即使我之前的 if 语句已经触发，我的 else 语句仍然会触发为什么会发生这种情况[重复]

Question

嗨，我是 C 新手，我正在编写一个基本的刽子手游戏，当我运行代码时，即使之前的 if 语句触发了 else 语句，为什么会发生这种情况

代码如下：

#include <stdio.h>

int main(int argc, char const *argv[]) {
  int Guesses = 0;
  int Completion = 0;
  char UserGuess;
  char Word[] = "fire";

  while (Guesses < 6) {
    if (Completion == 4) {
      printf("You Won\n");
      break;
    }

    printf("Please Enter Your Guess It Can Only Be A Letter Not A Word\n");
    printf("The Word Is 4 Characters Long\n");

    scanf("%c", &UserGuess);

    if (UserGuess == 'f') {
      printf("You Guessed One Of The Letters\n");
      printf("f_ _ _\n");
      Completion++;
    }

    if (UserGuess == 'i') {
      printf("You Guessed One Of The Letters\n");
      printf("_i_ _\n");
      Completion++;
    }

    if (UserGuess == 'r') {
      printf("You Guessed One Of The Letters\n");
      printf("_ _r_ \n");
      Completion++;
    }

    if (UserGuess == 'e') {
      printf("You Guessed One Of The Letters\n");
      printf("_ _ _e\n");
      Completion++;
    }
    else {
      printf("You Guessed The Letter Wrong try again\n");
      Guesses++;
    }
  }
}

Answer 1

看看你的if..else：

if (UserGuess == 'e') {
  printf("You Guessed One Of The Letters\n");
  printf("_ _ _e\n");
  Completion++;
}
else {
  printf("You Guessed The Letter Wrong try again\n");
  Guesses++;
}

如果您输入除“e”之外的任何字母，这将打印“You Guessed The Letter Wrong”。

您需要为所有条件添加if..else..if 链：

if (UserGuess == 'f') {
  printf("You Guessed One Of The Letters\n");
  printf("f_ _ _\n");
  Completion++;
} else if (UserGuess == 'i') {
  printf("You Guessed One Of The Letters\n");
  printf("_i_ _\n");
  Completion++;
} else if (UserGuess == 'r') {
  printf("You Guessed One Of The Letters\n");
  printf("_ _r_ \n");
  Completion++;
} else if (UserGuess == 'e') {
  printf("You Guessed One Of The Letters\n");
  printf("_ _ _e\n");
  Completion++;
} else {
  printf("You Guessed The Letter Wrong try again\n");
  Guesses++;
}
