Lets write a C program to check if user input character is an alphabet or not.

In C programming language, every character variable holds an ASCII value rather than the character itself.

Note: ASCII value range of lower case alphabets: ASCII value of a is 97. ASCII value of b is 98. ASCII value of c is 99. and so on till z .. ASCII value of z is 122.

ASCII value range of upper case alphabets: ASCII value of A is 65. ASCII value of B is 66. ASCII value of C is 67. and so on till z .. ASCII value of Z is 90.
