/*
 * Write a C program to input any character and check whether it is alphabet, digit or special character.
 *
 * Let us make a fresh definition again -
 *
 * A character is alphabet if it in given range a-z or A-Z.
 * A character is digit if it is in range of 0-9.
 * A character is special symbol character if it neither an alphabet nor a digit.
