C++

Create three recursive functions that accomplish the following:

Recursive Power Function this function will raise a number to a power. The function should accept two arguments, the number to be raised and the exponent. Assume that the exponent is a non-negative integer.

String Reverser function that accepts a string object as its argument and prints the string in reverse order.

Sum of Numbers this function accepts an integer argument and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 10 is passed as an argument the function will return the sum of 1, 2, 3, 4, 5 ... 10. Main should call each of the functions to show that they work correctly.
