Debug a small application
Find and fix all the bugs
Go over the next part of your project
Basic Debugging Tips:
Compile the program
If there are compiler errors, start by trying to fix the first (top-most) error.
Read the error message and examine the code at the line number it gives you.
Fix any warnings after fixing errors
Run the program
Use debug statements (std::cerr) to:
Check variable values
Determine the flow of the program
Be systematic and fix ONE bug at a time.
Re-compile and run the program after each potential fix.
We need to:
Copy the debug_lab2 directory from shared into your cs23001 folder
The program you've been given, pop_growth.cpp has multiple bugs. You may NOT use a third-party debugging tool (i.e., NO Visual Studio).
This program is designed to calculate the estimated population growth of a university over 5 years.
Users are prompted for the name of the university, the current population, and the percentage of growth.
Fix all of the bug(s) and re-run the program to confirm that you've fixed them all.
Example input and output:
$ make pop
$ ./pop
Enter the name of the university
Kent State University
What is the current population? 10000
What is the rate of growth? (e.g., for 10% enter 10) 20
Year New Population
1 12000
2 14400
3 17280
4 20736
5 24883
Final population of Kent State University is 24883
Done? (Y/N) y
Exiting...Remember that you can run this multiple times:
$ make pop
$ ./pop
Enter the name of the university
Kent
What is the current population? 5678
What is the rate of growth? (e.g., for 10% enter 10) 5
Year New Population
1 5961
2 6259
3 6571
4 6899
5 7243
Final population of Kent is 7243
Done? (Y/N) N
Starting again
------------------------------
What is the current population? 123
What is the rate of growth? (e.g., for 10% enter 10) 8
Year New Population
1 132
2 142
3 153
4 165
5 178
Final population of Kent is 178
Done? (Y/N) y
Exiting...Don't forget about errors:
$ make pop
$ ./pop
Enter the name of the university
The Venture Bros. University!
What is the current population? -1
./pop: Invalid Input Error!$ make pop
$ ./pop
Enter the name of the university
OSU
What is the current population? 7896
What is the rate of growth? (e.g., for 10% enter 10) foobar
./pop: Invalid Input Error!$ make pop
$ ./pop
Enter the name of the university
MIT
What is the current population? 9000
What is the rate of growth? (e.g., for 10% enter 10) 15
Year New Population
1 10350
2 11902
3 13687
4 15740
5 18101
Final population of MIT is 18101
Done? (Y/N) q
./pop: Invalid input
The program will exit
------------------------------The following should be true when you are done, NAMES MUST MATCH EXACTLY:
You have copied the debug_lab2 folder into your cs23001.
In the directory testing_2 you have the following files:
The fixed pop_growth.cpp file
There are NO executables in the repository.
Your program compiles, runs, and performs as specified, with any bug(s) fixed.
Your program follows the General Program Requirements.
