C++ Program to Check Whether a character is Vowel or Consonant.

Source Code

#include <iostream>

using namespace std;

int main()
{
    char c; // Declare a variable to hold the character

    cout << "Enter a character: "; // Prompt the user to enter a character
    cin >> c; // Read the character from the standard input stream

    if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u' || c == 'A' || c == 'E' || c == 'I' || c == 'O' || c == 'U')
        cout << c << " is a vowel" << endl; // Print "vowel" if the character is a vowel
    else
        cout << c << " is a consonant" << endl; // Print "consonant" if the character is a consonant

    return 0;
}

Code Explanation

This program declares a variable c of type char to hold the character entered by the user. It then uses the cout object to print a prompt asking the user to enter a character, and the cin object to read the character from the standard input stream.

To check if the character is a vowel, the program uses an if statement with a compound condition that checks if the character is equal to one of the ten vowels (a, e, i, o, u, A, E, I, O, U). If the character is a vowel, the program prints the message "is a vowel" using the cout object. If the character is not a vowel, the program prints the message "is a consonant" using the cout object.

What is a vowel or constant?

In the English language, vowels are a class of speech sounds that are pronounced with an open vocal tract and are relatively sonorous. There are five vowel letters in the English alphabet: a, e, i, o, and u.

Consonants are speech sounds that are pronounced with a partially or fully closed vocal tract and are less sonorous than vowels. All letters of the English alphabet except the five vowel letters (a, e, i, o, u) are consonants.

In linguistics, vowels and consonants are called phonemes, which are the smallest units of sound that can change the meaning of a word. For example, the words “bat” and “pat” have different meanings, but they differ only by one phoneme (the vowel sound).

Explain “||”operator working in C++.

The || operator evaluates the expressions expression1 and expression2 from left to right. If either of the expressions is true, the entire expression is true, and the operator returns a non-zero value. If both expressions are false, the operator returns 0.

Here is an example of using the || operator in an if statement:

int num1 = 10, num2 = 20;

if (num1 > 0 || num2 > 0) // test if either num1 or num2 is greater than 0
{
    cout << "At least one of the numbers is positive" << endl;
}

In this example, the condition num1 > 0 || num2 > 0 is evaluated as true, because num1 is greater than 0. Therefore, the code inside the if clause is executed, and the program prints "At least one of the numbers is positive" to the standard output stream.
