C++ Program to Calculate Average of Numbers Using Arrays
An array stores multiple values of the same data type. To find the average, we add all the numbers and then divide the total by how many numbers there are. In this article, we'll show you how to write a C++ program to calculate the average of numbers using an array. For example, if we have the numbers 40, 80, 10, 75, and 25, their total is 230, and the average is 230 / 5 = 46. Approaches for Calculating Average Using Arrays In C++, we can calculate the average of numbers in an array in two main ...
Read MoreC++ Program to Check Leap Year
A leap year contains one additional day, i.e february 29, to keep the calendar year synchronized with the earth's orbit around the sun. We will write a C++ program that checks whether a given year is a leap year or not. A year that is divisible by 4 is known as a leap year. However, years divisible by 100 are not leap years while those divisible by 400 are. Here is a list of some leap years and non-leap years: ...
Read MoreC++ Program to Generate Multiplication Table
In this article, we will show you how to write a C++ program to generate the multiplication table of a number. A multiplication table shows how a number is multiplied by 1 to 10 and helps define the multiplication operation for that number. Each row displays the result of multiplying the number by values from 1 to 10. For example, the multiplication table of 4 looks like this: 4 * 1 = 4 4 * 2 = 8 4 * 3 = 12 4 * 4 = 16 4 * 5 ...
Read MoreC++ Program to Display Factors of a Number
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 ...
Read MoreC++ Program to Check Whether a Number is Prime or Not
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 MoreC++ Program To Convert Decimal Number to Binary
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 MoreC++ Program to Make a Simple Calculator to Add, Subtract, Multiply or Divide Using switch...case
In this article, we'll show you how to write a C++ program to create a simple calculator that can add, subtract, multiply, or divide using a switch statement. The calculator works by taking two numbers(operands) and an operator (+, -, *, /) from the user, and then it performs the chosen operation. Lets understand it better with an example: Suppose the user enters: a = 5 and b = 4 Then, based on the chosen operator: If the operator is +, the result is 5 + 4 = 9 If the operator is -, the result is 5 ...
Read MoreC++ Program to Convert Binary Number to Decimal and vice-versa
In this article, we will learn how to convert a binary number to a decimal number and a decimal number to a binary number using C++. This means converting numbers like 5 or 10 into a format that uses only 0s and 1s, and also converting binary numbers back into decimal. Decimal number system has a base of 10 as it uses 10 digits from 0 to 9, while binary has a base of 2 as it uses only 0 and 1. Binary is used in computers because digital devices can only represent two states: on(1) and off(0). Example ...
Read MoreC++ Program to Find Factorial
In this article, we'll show you how to write a C++ program to find the factorial of a number. The factorial of a number is the result of multiplying all the positive integers from 1 to that number. It is written as n! and is commonly used in mathematics and programming. Let's understand this with a few examples: //Example 1 Input: 5 The factorial of 5 is: 5 * 4 * 3 * 2 * 1 = 120 Output: 120 //Example 2 Input: 6 The factorial of 6 is: 6 * 5 * 4 * 3 * 2 ...
Read MoreC++ Program to Find LCM
In this article, we'll show you how to find the LCM of two numbers in a C++ program. The LCM(Least Common Multiple) is the smallest positive number that is exactly divisible by both numbers. For example, if we take 4 and 5: The multiples of 4 are: 4, 8, 12, 16, 20, 24, ... The multiples of 5 are: 5, 10, 15, 20, 25, ... The first common multiple is 20, so the LCM of 4 and 5 is 20. Approaches to Find LCM in C++ We can find the LCM of two ...
