为什么C的格式化字符串有％c和％S两者兼而有之？ [英] Why does C's printf format string have both %c and %s?

问题描述

为什么C的格式化字符串兼得％C 和％S ？

Why does C's printf format string have both %c and %s?

我知道％C 重新presents单个字符和％S 重新presents字符的空终止字符串，但不会串再独自presentation够吗？

I know that %c represents a single character and %s represents a null-terminated string of characters, but wouldn't the string representation alone be enough?

推荐答案

大概区分之间的空结束的字符串和字符。如果他们只是有％S ，然后每一个字符，也必须以空值终止。

Probably to distinguish between null terminated string and a character. If they just had %s, then every single character must also be null terminated.

char c = 'a';

在上述情况下， C 必须以空值终止。这是我的假设，虽然：）

In the above case, c must be null terminated. This is my assumption though :)
