1. Type in the above program as square.cpp. Add a comment to include your names and date. Compile and run with different values.
2. Include a line that prints "Good bye!" before the program exits. This should only print once.
3. What symbol does || stand for in C++?
4. What happens if you answer "z" when asked if you want to square a number? Why?
5. Summarize how the above loop works, for example _____ and _____ cause the loop to continue, __________ causes the loop to end.
6. Modify the program to change the || to &&. What is the result? Why? Change it back when you have answered the question
7. Comment out (put // at the front of the line) the line that is labeled 1 or START. What happens (is there an error?)? Why? Restore the lines, or un-comment, by removing the // after you have answered the question.
8. Comment out the line "cin >> ans" near the end of the program. What happens, why? Un-comment the lines after you have answered the question.
