推荐答案

您的 scanf 声明是错误的。数组名称已经是指针，因此不需要地址（&）运算符：

Your scanf statement is wrong. Array names are already pointers so do not need the addressof (&) operator:

// wrong
while (scanf("%s %s", &op, &buf) == 2)
// should be just:
while (scanf("%s %s", op, buf) == 2)

您还需要刷新输入下一个 scanf ，因为仍然会有一个要读取的换行符。

You also need to flush the input for the next scanf, as there will still be a newline character to be read.
