string::find( char c, size_type pos = 0 ) returns the index of the first occurrence of c in the string beginning at index pos. string::substr( size_type pos = 0, size_type n = npos ) returns the substring of n characters beginning from, and including, the character at index 'pos...

The strrchr() function finds the last occurrence of c (converted to a char) in string. The ending NULL character is considered part of the string. Note: When COMPACT is specified, the compiler does not generate inline code for this function. In this case, you need to take either of th...
