    In this video, we will see a C++ Program to Calculate the Power of a Number.

    To calculate the power of a number we use two different methods:

    1. User defined function
    2. In-built function [pow()]

    User-defined function: Here we make a Power() which is a user-defined function and calculate the power using a While loop.
    In-built function [pow()]: Given two numbers base and exponent, pow() function finds x raised to the power of y i.e. xy. pow() is function to get the power of a number, but we have to use #include in C++ to use that pow() function, then two numbers are passed.

    Syntax: pow(base,exponent);
    Pow() parameters:
    1) Base: the base value
    2) Exponent: exponent of the base

    Pow() return value:
    1) Result of base exponent
    2) 1.0 if exponent is 0.
    3) 0.0 if base is 0.

    Example:
    pow(4 , 2); Then we will get the result as 4^2, which is 16.

    Input : x = 2, n = 3
    Output : 8

    Input : x = 7, n = 2
    Output : 49
