int find_first_of(char c, int start = 0): 查找字符串中第1个出现的c,由位置start开始。 如果有匹配,则返回匹配位置;否则,返回-1.默认情况下,start为0,函数搜索 整个字符串。 int find_last_of(char c): 查找字符串中最后一个出现的c。有匹配,则返回匹配位置;否则返回-1. 该搜索在字符末尾查找匹配...

std::string::find_last_of 是一个字符串类成员函数,用于查找字符串中任何字符最后一次出现的索引。如果该字符存在于字符串中,则返回该字符在字符串中最后一次出现的索引,否则返回 string::npos。头文件: #include < string > 模板类 template < class T > size_type find_last_of(const T& t, size_type...

The C++ std::string::find_last_of() function is used to locate the last occurrence of any character from a mentioned set within a string. It searches the string from the end towards the beginning, returning the index of the last character found that matc
