There are various character handling functions in C++ which provide facility to handle character in different ways. C++ provides #include<ctype.h> header file for character handling. All character functions have defined in #include<ctype.h> header file . \u201cctype\u201d means charater type. Character Functions isalnum() :- This function is used to check whether a character is a letter or a digit i.e alphanumeric or not.
