We can redefine or overload most of the built-in operators available in C++. Thus a programmer can use operators with user-defined types as well, this process is operator overloading. Overloaded operators are functions with special names the keyword operator followed by the symbol for the operator being defined. Like any other function, an overloaded operator … Read more

## Powerset Algorithm C++

Today we are going to talk about the Powerset Algorithm C++: What is PowerSet? A powerset of a given set is the combination of all subsets, including the empty subset and the set itself. Suppose we have the following set: {1,2,3}. Its powerset would be: {1,2,3} {1,2} {1,3} {2,3} {1} {2} {3} Creating an algorithm … Read more

## C program without main ()

## Add two numbers without using arithmetic operators in C++

Add two numbers without using Arithmetic operators: Write a function Add( ) that returns sum of two integers. The function should not use any of the arithmetic operators (+, ++, –, -, .. etc). Sum of two bits can be obtained by performing XOR (^) of the two bits. Carry bit can be obtained by … Read more

## Find last prime number in C++

Here you can find the program to find last prime number in C++ before the entered number. Let’s discuss what logic we can use here. How it works: User enters a number. Start one for loop from ‘number – 1’ in backward direction and another from 2 in forward direction. Check if the number is … Read more
