1) In computing a number to the power of another such as xn,
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 xn. Of course, then
you need to compute xn-1 . So you will follow the same
procedure until you get to the x0, which is actually equal to
1. Use this method to compute 43. 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.
