Write a program to read from the user a single line $($up to $255$ characters$)$ at a time and splits the line into lexemes, if possible. The program will determine whether each lexeme is a reserved word, an arithmetic operator, a special symbol, a number, or an identifier. The following arrays are already given:

char reservedWords$[4][10]=\{$cin$>>,$for$,$int$,$while$\}$;

char operator$[6][2]=\{+,-,*,/,++,--\}$

char special$[7][3]=\{>,=,$;$,(,),>=,,\}$;

A number is an unsigned integer or a signed integer.

An identifier starts with a letter or $\_$ followed by any number of letters, $\_,$ and digits, and excludes any reserved word.

For each lexeme check whether it is a reserved word. If not, check whether it is a special symbol. If not, check whether it is a number. If not, check whether it is an identifier. If none of these, display $$invalid$.$ The program must be case insensitive. Save it as Prog$3$Sample I$/$O:
