All the questions this week ask for programs in C. Perfection will not be expected, but please try to write really good C. (Remember that the language the text calls C++ is for our purposes just the same as C.)
1. Write a C program that will compute the sum of all the non-negative integers in a 64-element integer array called A (which may contain negative integers). Use a while loop to go through the array. Put the answer in an integer variable named answer.
2. Now solve the same problem as question 1, but use a for loop instead of a while. Here is that cheat-sheet on for loops.
3. Write a program in C to find the biggest and smallest integers in a 100-element positive integer array named Ralph, and then compute the remainder of the biggest divided by the smallest. The C operator % is just what you need: m % n is the remainder of m divided by n. First, do this by using two different loops, one for the biggest and one for the smallest. Use either for or while loops. Put the answer in a variable named gretchen.
4. Now solve the same problem as question 3, but use just one loop.
Extra credit: Visit http://www.mindspring.com/~alanh/life/ and experiment with some Game of Life patterns. Try different speeds and zoom factors. From the Open menu-button you can select different pre-cooked starting patterns, some of which have amazing behavior. Write and turn in a short paragraph saying why one of these patterns particularly intrigued you.
