Logic To Find Lowercase Alphabet or Not using Conditional Operator

Using Conditional Operator we write the condition, if user entered character is greater than or equal to ASCII Value 97(which corresponds to lowercase character a) and less than or equal to ASCII Value 122(which corresponds to lowercase character z).

If the condition is true, then user entered character is lower case English alphabet, if not, then its not a lowercase English alphabet.
