从C字符串中去除第一和最后一个字符 [英] Strip first and last character from C string

问题描述

我有一个C字符串，它看起来像NMY stringP，其中N和P可以是任何字符。我怎么可以编辑成我的字符串用C？

I have a C string that looks like "Nmy stringP", where N and P can be any character. How can I edit it into "my string" in C?

推荐答案

要删除的第一个字符点到第二个字符：

To "remove" the 1st character point to the second character:

char mystr[] = "Nmy stringP";
char *p = mystr;
p++; /* 'N' is not in `p` */

要删除的最后一个字符替换为一个'\\ 0'

To remove the last character replace it with a '\0'

p[strlen(p)-1] = 0; /* 'P' is not in `p` (and it isn't in `mystr` either) */
