c - C 语言中 else 没有前面的 if

Question

这个问题已经有答案了:

C language: if() with no else(): using braces fails (5 个回答)

已关闭 6 年前。

我知道 else 语句不应在 if 语句末尾有分号。

目标是使这个 if/else 语句起作用，以便如果答案不是 Y 或 y，则打印 else 语句。我的问题是:

• 到底需要做什么来纠正这个问题？

代码如下:

if (answer=='Y'|| 'y')
scanf(" c", &answer);
printf("\n Great! Keep listening to music. I'm sure your mood will improve.");
else printf("\n Try listening to some music that you enjoy!");
}

Answer 1

The objective is to make this if/else statement work,

您的代码中缺少花括号。

scanf(" %c", &answer);
 if (answer=='Y'|| answer == 'y') {
     printf("\nGreat! Keep listening to music. I'm sure your mood will improve.\n");
 }
 else {
     printf("\nTry listening to some music that you enjoy!\n");
 }
