8. Some programs use more memory in defining procedures, but in what circumstances do
procedures save memory space?
9. Name two ways by which information can be passed from main program to a procedure. (two
points)
10. What is an actual parameter?
11. What is a formal parameter?
PROBLEMS ON CHAPTER 7
1. Write a procedure which outputs one of the four suits: 'Hearts', 'Clubs: 'Diamonds' or 'Spades'.
Call the procedure five times to get five random suits.
2. Write another program for problem 1 using a number in the range 1 to 4 as a parameter to
determine the output word. If you have already done this, then try writing the program without
parameters.
3. Write a procedure which will output the value of a card that is a number in the range 2 to 10 or
one of the words 'Ace', 'Jack' 'Queen', 'King'.
4. Write a program which calls this procedure five times so that five random values are output.
5. Write the program of problem 3 again using a number in the range 1 to 13 as a parameter to be
passed to the procedure. If this was the method you used first time, then try writing the program
without parameters.
6. Write the most elegant program you can, using procedures, to output four hands of five cards
each. Do not worry about duplicate cards. You can take elegance to mean an appropriate mixture
of readability shortness and efficiency. Different people and/or different circumstances will place
different importance on these three qualities which sometimes work against each other.
