3. Write a program to find the factorial of a given number by using a function in C++ programming language. Note: factorial(n)=1*2*3*....*n for n>1, factorial(0)=factorial(1)=1

Write a C++ function factorial that takes an integer, n, and returns the value of n factorial (a.k.a., n!): When n is positive, n! = 1 * 2 * 3 * ... * n.  For example, 5! = 1 * 2 * 3 * 4 * 5 = 120. When n is zero, n! is defined to be 1. When n is negative, n! is undefined. You may assume that the parameter n will not be negative for this problem.

Q. Given two matrices, Write a function to check whether the two matrices are identical or not. if all the elements in the respective positions of the two matrices are same, then say that they are identical and if not same then say that they are not identical. Write a program in c++ for this problem statement.

language: Python   Problem:  Write a recursive function power(x, n), where n is 0 or a postive integer. For example, power(2, 10) will return 1024. Write a suitable base case, and for the general case use the idea that xn = x * x n-1.
