The string class provides strings handling functions that allow you to find characters within a string, extract sequential sequences of characters (called substrings ), and delete and add them in a string. We'll cover some of the main functions.

All the string handling functions are prototyped in: #include The common functions are described below: char *stpcpy (const char *dest,const char *src)-- Copy one string into another.int strcmp(const char *string1,const char *string2)-Compare
