Lab 3.1
Step 1 Identify potential problems.
Variable Name Problem Yes/No if yes, what’s wrong?
Declare Real credits Taken No
Declare Int cedits Left Yes We need to be able to use decimal as well.
Declare Real studentName No
Constant Real creditsNeeded=90 No

Step 2
What’s wrong with this calculation Set credits-Left = credits-Taken – credits-Needed It should be: Set credits-Left = credits-Needed – credits-Taken
Step 3
Write the exact output you would expect from the following code if the user of the program enters “John Brown”. Display “The student’s name is “, studentName Output will be “The student’s name is, John Brown
Step 4
Write the exact output from the following line of code if user of the program enters John Brown and they have taken 20 credits so far. Display “The Network Systems Administration degree is awarded after 90 credits and “, studentName, “ has “, creditsLeft, “ left to take before graduation.” Output “ The Network Systems Administration degree is awarded after 90 credits and John Brown has 70 left to take before graduation.
Step 5
1. //Provide documentation on line 2 of what this program does
2. //This program displays student information and degree program information
3. //Declare variables on lines 4, 5, 6, and 7
4. //Declare Real studentName
5. //Declare Real creditsTaken
6. //Constant Real creditsNeeded = 90
7. //Declare Real creditsLeft
8. //Ask for user input of studentName and creditsTaken
9. //Display “ What is the students name?”
10. //Input studentName
11. //Display “ How many credits have been taken?”
12. //Input creditsTaken
13. //Calculate remaining credits on line 14
14. //Set creditsLeft = creditsNeeded – creditsTaken
15. //Display student name and credits left on line 16 and 17
16. //Display studentName
17. //Display creditsLeft
