Homework 10

Details

1. (6 points) Given that there is a function pow(a,b) that computes a^b, write a function int sumCubes(int n) that uses a for loop to compute 1³+2³+3³+...+n³.
2. (3 points) Write a function boolean isSet(int n,int b) that returns true if the bth bit of n is 1 and false otherwise. We order bits from right to left, so isSet(n,0) determines whether or not n is odd or even.
   It might help you to know that there is an operator a>>b that shifts a to the right by b bits, discarding the low order bits. For instance, 8 >> 2 gives you 2 and 15 >> 2 gives you 3.
