Code Explanation :


you have the knowledge of following topics to understand this example:

In C programming, a character variable holds an ASCII value (an integer number between 0 and 127) rather than that character itself.

The lowercase alphabet's ASCII value lies between 97 and 122. And, The uppercase alphabet's ASCII value lies between 65 to 90.

If the ASCII value of the user's entered character is within the range of 97 to 122, or between 65 and 90, that number is an alphabet.

In this program, We are using 'a' instead of 97 and also 122 instead of 'z'.

Note: It would be better to check whether a character is an alphabet or not using the function isalpha().

Algorithm

Step 1 : start
Step 2 : Declare character c
Step 3 : Read c
Step 4 : IF ((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z')) THEN
            Print Character is an alphabet
        ELSE
            Print Character is not an alphabet
Step 5 : end
