append()在字符串的末尾添加文本assign()为字符串赋新值at()按给定索引值返回字符begin()返回一个迭代器，指向第一个字符c_str()将字符串以C字符数组的形式返回capacity()返回重新分配空间前的字符容量compare()比较两个字符串copy()将内容复制为一个字符数组data()返回内容的字符数组形式empty()如果字符串为空，返回真end()返回一个迭代器，指向字符串的末尾。（最后一个字符的下一个位置）erase()删除字符find()在字符串中查找字符find_first_of()查找第一个与value中的某值相等的字符find_first_not_of()查找第一个与value中的所有值都不相等的字符find_last_of()查找最后一个与value中的某值相等的字符find_last_not_of()查找最后一个与value中的所有值都不相等的字符get_allocator()返回配置器insert()插入字符length()返回字符串的长度max_size()返回字符的最大可能个数rbegin()返回一个逆向迭代器，指向最后一个字符rend()返回一个逆向迭代器，指向第一个元素的前一个位置replace()替换字符reserve()保留一定容量以容纳字符串（设置capacity值）resize()重新设置字符串的大小rfind()查找最后一个与value相等的字符（逆向查找）size()返回字符串中字符的数量substr()返回某个子字符串swap()交换两个字符串的内容

你说错了,应该是String.h头文件.想知道里头有多少函数,你可以直接在编译器的安装目录搜:String.h文件然后打开来查不就知道了.
