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 design and debuggers can have…
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 = x xor y y1 =…
Wap in C++ to Draw hollow Diamond shape in C++ For other triangle and diamonds shapes see -> Patterns and Shapes in C++ PROGRAM: #include<iostream> using namespace std; int main() { int size; cout<<“Enter size of Diamond: “; cin>>size; int z=1; for ( int i=0; i<=size; i++) { for (int j=size; j>i; j-) { cout<<” “; // printing space here…
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 1-12 concept int year =…
What is Factorial of a number? Factorial of a number ‘n’ is the product of all positive integers less than or equal to n, denoted by ‘n!’. For example find factorial of 5. 5! = 5 x 4 x 3 x 2 x 1 = 120 Now let’s see the program to find factorial of a number in C++ PROGRAM: #include<iostream>…
Write a program to find Armstrong Number C++? A number is armstrong if the sum of cubes of individual digits of a number is equal to the number itself. For example 371 is an armstrong number, as 33 + 73 + 13 = 371. Some other armstrong numbers are: 0, 1, 153, 370, 407. PROGRAM: #include <iostream> using namespace std;…
C++ Program to find area of any triangle using Herons Formula PROGRAM: #include<iostream> #include<math.h> using namespace std; int main() { float first,second,third; float s,area; cout<<“Enter size of each sides of triangle”<<endl; cout<<“Enter size for First Side = “; cin>>first; cout<<“Enter size for Second Side = “; cin>>second; cout<<“Enter size for Third Side = “; cin>>third; s = (first+second+third)/2; area =…
