Raising a number n to a power p is the same as multiplying n by itself p times. Write a function called power() that takes a double value for n and an int value for p, and returns the result as a double value. Use a default argument of 2 for p, so that if this argument is omitted, the number n will be squared. Write a main() function that gets val ues from the user to test this function. .....i want to understand what he want?????i lost my mind

Seems like you are missing some core concepts. Have you tried going a few chapters back and try to do the earlier exercises? Or you could try another book, I suggest C++ Primer by Josée Lajoie and Stanley B. Lippman.
Anyway, one possible solution would be this.

He wants you to make a function which can calculate power
e.g.: n=2 p=4 => n^p = 2^4 = 2*2*2*2 =16 and this you have to make in a function with paramters (n as double parameter and p as int parameter) the returnvalue has to be the result of the calculation in double format. and if p value gets obmitted you should make a default value of 2 so he can calculate n^2
