Program to Check Vowel or Consonant Using Switch Case

Problem Statement

Switch case is a programming syntax, that provides an alternative elegant way to represent conditional base statements in programming languages. Mostly all the popular programming languages support switch-case statements.

Here, we have a problem statement where we need to write a script or program in C++, C, and Python that checks if a user-entered character or alphabet is a vowel or not.

For example

Input:
a
Output
It is a Vowel

C Program to Check Vowel or Consonant Using Switch Case

#include <stdio.h>
int main()
{	
	char chr;
	
	//input chracter
	printf("Enter the Alphabet: ");
	scanf("%c", &chr);
	
	switch(chr)
            {
                case 'a':
                case 'A':

                case 'e':
                case 'E':

                case 'i':
                case 'I':

                case 'o':
                case 'O':

                case 'u':
                case 'U':
                	printf("----------------It is a Vowel-------------");
               		break;
                default:
                	printf("++++++++++++++It is not a Vowel+++++++++++");
       		 }
	
	return 0;
}

Output

Enter the Alphabet: B
++++++++++++++It is not a Vowel+++++++++++

C++ Program to check given Alphabet is a vowel or not using switch case:

#include<iostream>
using namespace std;
int main()
{
	char chr;
    cout<<"Enter an Alphabet: "; cin>>chr;

    switch(chr)
                {
                case 'a':
                case 'A':

                case 'e':
                case 'E':

                case 'i':
                case 'I':

                case 'o':
                case 'O':

                case 'u':
                case 'U':
                cout<<"----------------It is a Vowel-------------";
                break;
                default:
                cout<<"++++++++++++++It is not a Vowel+++++++++++";
        }
	
	return 0;
}

Output:

Enter an Alphabet: A

----------------It is a Vowel------------

Python Program to check given Alphabet is a vowel or not using switch case:

Unfortunately, Python 3.9 and older versions do not support the switch-case statement, so instead of the switch case, we can use Python if..else statements.

# input alphabet
char = input("Enter an Alphabet: ")

# check for the VOWEL
if char in 'aeiouAEIOU':
    print("----------------It is a Vowel-------------")
else:
    print("++++++++++++++It is not a Vowel+++++++++++")

Output

Enter an Alphabet: I
----------------It is a Vowel-------------

Wrapping Up!

Writing a program to check if the user entered character is an alphabet or not is a trivial task, and in the above tutorial we have demonstrated how can you use C, and C++ switch-case statements to solve the problem.

By looking at the program, even a non-programmer can tell what the program is supposed to do, that's what switch-case provides to the programming language. For Python, we do not have support for switch-case so we implemented the program using if..else statement.
