ennumeration/namespace code

I am a new member, and have been taking c++ classes since January of this year. I am trying to create the program that generates a student status report from the text file. I can get the program to execute, but it won't display the data from the text files, nor the results thereafter.


The following is a .txt file:

John K. Doe
3460 25
Susan S. Andrews
3987 72
Marylin Monroe
2298 87
Arthur C. Gaston
2894 110

 /*

class_level tys::deriveClassLevel (int num_of_credits)		//derive the class level based on a two year school policy.

}


I am trying to output the following while running namespace fys:

John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior

...and while running namespace tys:

John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Sophomore
Arthur C. Gaston 2894 110 Sophomore

Any suggestions will be appreciated :)

I have the feeling that there are some misunderstandings...

For now: move line 49 inside the loop above and do not exclude the ignore statement

I made some updates to the code, and with some help, I have the code logically flowing. The program is now able to read from the text; however, it cannot calculate what level a particular student is in. It could be something that it's lacking.

Here is the updated program at this time:

The original deriveClassLevel(...) functions (with return) was correct
klanier (4)
I might of overdone it when changing the deriveClassLevel(...), thanks coder777.
