C++ program to check whether a character is vowel or consonant - My CS Tutorial

In this tutorial we will learn how to write a C++ program that check the character is vowel or consonant.
Create this program we will use if else statement.

As we know that a,e,i,o and u are vowels and others are consonant in alphabets table.

Explanation:

In this program we will use two data types as char and int data type.

After it we will enter a character.

The character entered by the user is stored in variable c.

The isLowerCaseVowel evaluates to true if c is a lowercase vowel and false for any other character.

Similarly, isUpperCaseVowel evaluates to true if c is an uppercase vowel and false for any other character.

If both isLowercaseVowel and isUppercaseVowel is true, the character entered is a vowel , if not the character is a consonant.

C++ program code

#include <iostream>

using namespace std;

int main()

{

    char c;

    int isLowercaseVowel, isUppercaseVowel;

    cout << "Enter an alphabet: ";

    cin >> c;

    

    // evaluates to 1 (true) if c is a lowercase vowel

     

    isLowercaseVowel = (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u');

    

    

    // evaluates to 1 (true) if c is an uppercase vowel

    

    

    isUppercaseVowel = (c == 'A' || c == 'E' || c == 'I' || c == 'O' || c == 'U');

    

    

    // evaluates to 1 (true) if either isLowercaseVowel or isUppercaseVowel is true

    

    

    if (isLowercaseVowel || isUppercaseVowel)

        cout << c << " is a vowel.";

    else

        cout << c << " is a consonant.";

    return 0;

}

OUTPUT 1:

OUTPUT 2:

In first output the input value of alphabet is   I
And the result is

I is a vowel.


In second output the input value of alphabet is   h
And the result is

h is consonant.
