- Get Hello World to work.
- Personalize the Hello World program with your
name so that it tells you Hello rather than the somewhat generic
"World."
- Write a program that produces the following
output:
Hello World!
It's been nice knowing you.
Goodbye world!
- Write a program that prints all the integers
between 0 and 36.
- Imagine you need to open a standard
combination dial lock but don't know the combination and don't have a
pair of bolt cutters. Write a program that prints all possible
combinations so you can print them on a piece of paper and check off
each one as you try it. Assume the numbers on the dial range from zero
to thirty-six and three numbers in sequence are needed to open the lock.
- Suppose the lock isn't a very good one and any
number that's no more than two away from the correct number in each
digit will also work. In other words if the combination is 17-6-32, then
18-5-31, 19-4-32, 15-8-33 and many other combinations will also open the
lock. Write a program that prints out a minimal list of combinations you
would need to try to guarantee opening the lock.
- Write a program that randomly fills a 10
component array, then prints the largest and smallest values in the
array.
- Hand in the first page of a print out of the
documentation for the
