Prerequisites

Before starting with this tutorial, we assume that you are the best aware of the following C programming topics:

  • Operators in C Programming.
  • Basic Input and Output function in C Programming.
  • Basic C programming.
  • Conditional Statements in C programming.

What is a character?

The character is a single alphabetical entity in the English language and in any word. These letters can be both capital & small or uppercase & lowercase.

For Example:-

In the “Hello” word the there are five characters they are as follows

Here,

“H” is an uppercase letter.

“e” is a lowercase letter.

“l” is a lowercase letter.

“l” is a lowercase letter.

“o” is a lowercase letter.

Algorithm:-

Program to Check the Character is Lowercase or Uppercase Alphabet

First, will take the character in input from the user. Then will pass that character in the conditional statements to find whether it is an upper case character or in lowercase.

With the help of this program, we can Check the Character in Lowercase or Uppercase Alphabet.

Program Code:-

Output:-

In the above program, we have first initialized the required variable.

  • chr = it will hold the character value for the input.

Input character from the user.

Finding the character is in upper case or lower case.

Printing output for the program.

In this tutorial we have learn about the C Program to Check the Character is Lowercase or Uppercase Alphabet and its application with practical example. I hope you will like this tutorial.
