Get started

Log on to Odin.

Change to your 2010/2 folder.
Name your program lab2a.cpp

Follow along to write a program.

Working with variables...

 1. A variable x starts with the value 0.
 2. A variable y starts with the value 5.
 3. Add 1 to x.
 4. Add 1 to y.
 5. Add x and y, and store the result in y.
 6. Display the value in y on the screen.

    What value did you get in y?

 7. A variable i starts with the value 10.
 8. A variable j starts with the value 2.
 9. A variable k starts with the value 4.
10. Store the value of i times j in i.
11. Store the value of j times k in k.
12. Add i and k, and store the result in j.
13. Display the value in j on the screen.
    
    What value did you get in j?

14. A variable a starts with the value 1.
15. A variable b starts with the value 10.
16. A variable c starts with the value 100.
17. A variable x starts with the value 0.
18. Store the value of c times 3 in x.
19. Add the value of b times 6 to the value already in x.
20. Add the value of a times 5 to the value already in x.
21. Display the value in x on the screen.

    What value did you get in x?

Part 2 - Write these programs yourself

   Each golfer played 9 holes.
   Enter all the scores.

2. Add up the total for each golfer.

   Enter the scores for player 2: 3 4 5 4 3 4 5 4 3
   Enter the scores for player 3: 4 2 3 4 5 4 2 4 2
   Enter the scores for player 4: 5 2 4 5 2 4 5 3 4

5. To run and test your program...

   Create a file in your directory named: 2010/2/golf_scores.txt

   Run your program like this:
   
	  ./a.out < golf_scores.txt

6. The output will look something like this

   Final score of each golfer
      player 1: 36
      player 2: 35
      player 3: 30
      player 4: 34
