Union and Intersection of Arrays C++

Union and Intersection of Arrays Let us suppose we have two sorted Arrays int Arr1[]={1, 3, 4, 5, 7}; int Arr2[]={2, 3, 5, 6}; then UNION will be: {1, 2, 3, 4, 5, 6, 7} INTERSECTION : {3, 5} C++ Program for UNION of arrays: #include<iostream> #include<stdio.h> using namespace std; /* Function prints union of […]

Median of two sorted arrays Program C++

What is Median? In probability theory and statistics, a median is described as the number separating the higher half of a sample, a population, or a probability distribution, from the lower half. The median of a finite list of numbers can be found by arranging all the numbers from lowest value to highest value and […]

Multiple Inheritance in c++ example

What is Multiple Inheritance? Multiple inheritance is a feature of some object-oriented computer programming languages in which an object or class can inherit characteristics and features from more than one parent object or parent class. Deriving directly from more than one class is usually called multiple inheritance. Since it’s widely believed that this concept complicates the […]

Effective way to Swap two numbers using xor

One of the most effective way to swap two numbers is by using XOR gate. We do not any third variable to store value, therefore it has lower space complexity than the traditional swapping program using third or temporary variable. How it works? To understand this trick, break the statements into unique values: x1 = […]

Program to display current Date and Time C++

To show current Date and Time in a program just use “localtime()” function. Calculation of day, month and year is explained. PROGRAM: #include <time.h> time_t theTime = time(NULL); struct tm *aTime = localtime(&theTime); int day = aTime->tm_mday; int month = aTime->tm_mon + 1; // Month is 0 – 11, add 1 to get a jan-dec […]
