C语言标准库提供了一个非常方便的函数strstr(),用于查找子字符串。这个函数在string.h头文件中定义。strstr()函数的基本用法是传递两个字符串,返回一个指向第一个匹配子字符串的指针。如果没有找到匹配的子字符串,则返回NULL。 示例代码 #include <stdio.h> ...
5.处理字符串常用string.h里面的字符串函数 … 字符指针数组查找字符串: 1.遍历数组,比较字符串大小判断是否相等 int str_search1(const char*dststr, const char**srcstr, int num) //适用于全部字符串(字符数组和字符串常量) { int i; for (i = 0; i < num; i++) ...
