C++ 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 Implement Set_Difference in STL
The Set Difference is an operation used to find all elements present in the first set but not in the second. In this article, we will learn how to use the set_difference algorithm from the Standard Template Library (STL) in C++ to find the difference of two sets. What is Set Difference? The set difference is an arithmetic operation performed between two sets to find all elements present in the first set but not in the second. In C++, we have set_difference which is a built-in algorithm provided by C++ STL that computes the set difference of two sorted ...
Read MoreC++ Program to Implement Set_Intersection in STL
The Set Intersection is an operation used to find all elements that are common in both sets. In this article, we will learn how to use the set_intersection algorithm from the Standard Template Library (STL) in C++ to find the intersection of two sets. What is Set Intersection? The set intersection is an arithmetic operation performed between two sets to find all elements that are common in both sets. In C++, we have set_intersection which is a built-in algorithm provided by C++ STL that computes the intersection of two sorted ranges of sets. That is, it returns the elements ...
Read MoreC++ Program to Perform the Shaker Sort
Shaker sort is a variation of bubble sort and is both a stable and comparison based sorting algorithm. The shaker sort is also known as cocktail sort or bidirectional bubble sort as it sorts the array in both directions. In this article, we have an unsorted array. Our task is to implement the shaker sort in C++ to sort the given array. Example The following example sorts the unsorted array using the shaker sort: Input: array = {5, 1, 4, 2, 8, 0, 2} Output: Sorted array = {0, 1, 2, 2, 4, 5, 8} The ...
Read MoreC++ Program to Perform Stooge Sort
Stooge Sort is a recursive sorting algorithm used to sort the given data. The stooge sort divides the array into two overlapping parts, 2/3 each and then sort the array in three steps by sorting first then second and again first part. The worst case time complexity of this algorithm is O(n^2.7095). In this article, we have an unsorted array. Our task is to implement the stooge sort algorithm for sorting the given array in C++. Example Here is an example of sorting the given array using stooge sort: Input: array = {5, 3, 8, 4, 2, 7} ...
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 ...
