Operator overloading can be done with most of the built-in operators in C++. The overloaded operators are functions with the keyword operator followed by the operator symbol that is defined. The overloaded operators have a return type and a parameter list like any function.A program that subtracts complex numbers using ... Read More

Multiplication of two numbers a and b yields their product. Value of a is added as many times as the value of b to get the product of a and b.For example.5 * 4 = 20 7 * 8 = 56 9 * 9 = 81Program to Multiply two Numbers ... Read More

A prime number is a whole number that is greater than one and the only factors of a prime number should be one and itself.Some of the first prime numbers are −2, 3, 5, 7, 11, 13 ,17A program to check if a number is prime or not using a ... Read More

Factorial of a non-negative integer n is the product of all the positive integers that are less than or equal to n.For example: The factorial of 7 is 5040.7! = 7 * 6 * 5 * 4 * 3 * 2 *1 7! = 5040Let us see the code to ... Read More
