Answer the following questions in writing.

1) In computing a number to the power of another such as x^{n},
you may use a procedure in which you use the number to the power of n-1
first then multiply it by x to get x^{n}. Of course, then
you need to compute x^{n-1 }. So you will follow the same
procedure until you get to the x^{0}, which is actually equal to
1. Use this method to compute 4^{3}. Show all the steps.

2) Write a C++ code segment that takes a string and displays the characters of that string one per line. Assume that the string is already read in from the keyboard.

Example:

Input: Hello

Output:

H

e

l

l

o
