In this article, we'll show you how to write a C++ program to check if a given character is a vowel or a consonant. Vowels are the letters 'a', 'e', 'i', 'o', 'u'(both uppercase and lowercase), and all other alphabetic characters are consonants. For example, if we input the character 'a', the program will output 'vowel'. If we input 'b', it will output 'consonant'. In C++, there are different ways to check if a character is a vowel or consonant. Below are the common methods: Using an if-else statement ... Read More

A number is even if it is divisible by two and odd if it is not divisible by two.Some of the even numbers are −2, 4, 6, 8, 10, 12, 14, 16Some of the odd numbers are −1, 3, 5, 7, 9, 11, 13, 15, 17Check Whether Number is Even or Odd using ModulusA program to check whether number is even or odd using modulus is as follows.Example Live Demo#include using namespace std; int main() {    int num = 25;    if(num % 2 == 0)    cout

There are two ways to create a program to swap two numbers. One involves using a temp variable and the second way does not use a third variable. These are explained in detail as follows −Program to Swap Two Numbers using temp VariableThe program to swap two numbers using a temp variable is as follows.Example Live Demo#include using namespace std; int main() {    int a = 10, b = 5, temp;    temp = a;    a = b;    b = temp;    cout

Data Types in C++There are many data types in C++ but the most frequently used are int, float, double and char. Some details about these data types are as follows −int - This is used for integer data types which normally require 4 bytes of memory space.float - This is used for storing single precision floating point values or decimal values. float variables normally require 4 bytes of memory space.double - This is used for storing double precision floating point values or decimal values. Double variables normally require 8 bytes of memory space.char - This is used for storing characters. ... Read More

Quotient and Remainder are parts of division along with dividend and divisor.The number which we divide is known as the dividend. The number which divides the dividend is known as the divisor. The result obtained after the division is known as the quotient and the number left over is the remainder.dividend = divisor * quotient + remainderFor Example: If 15 is divided by 7, then 2 is the quotient and 1 is the remainder. Here, 15 is the dividend and 7 is the divisor.15 = 7 * 2 + 1A program to find quotient and remainder is as follows:Example Live Demo#include ... Read More

In this article, we'll show how to add two numbers using C++ and display the result. Adding two numbers is a basic arithmetic operation, meaning we combine their values to get a total. We will see different methods to solve this. Different Ways to Add Two Numbers in C++ In C++, there are various approaches to add two numbers, each approach using its own cases and advantages. Below are the mentioned list: Using Addition Operator Using User Input Using Increment and Decrement Operators ... Read More

In a computer system, the binary number is expressed in the binary numeral system while the decimal number is in the decimal numeral system. The binary number is in base 2 while the decimal number is in base 10. Examples of decimal numbers and their corresponding binary numbers are as follows: Decimal Number ... Read More

The objects “cin” and “cout” are used in C++ for input and output respectively. cin is an instance of the istream class and is attached to the standard input device such as the keyboard. cout is an instance of the ostream class and is connected to the standard output device such as the display screen.A program that prints the number entered by the user is as follows −Example Live Demo#include using namespace std; int main() {    int num;    coutnum;    cout

A prime number is a whole number greater than one and the only factors of a prime number should be one and itself. For example, 2, 3, 5, 7, and 11 are prime numbers. Our task is to write a C++ program that checks if a given number is prime or not. We will cover different approaches to solve this problem. We'll cover the following methods for checking whether a number is prime or not: Using a Simple Loop Using the Square Root Method Using ... Read More

A factor is a number that divides a given number completely without leaving a remainder. In this article, we'll show you how to display all the factors of a number using different methods in C++. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. In this article, we will look at two ways to find and display the factors of a number: Basic Iterative Approach Optimized Square Root Approach Factors of a Number Using Iterative (Basic) Approach In this approach, we use loop to go ...
