Debugging a C++ program

[L6Rz8vqX]

Hi, I am new at programming and am completely overwhelmed in my class. Would any one please help show me what/how needs to be debugged in this program? Any help would be appreciated!

Thank you

There is also a debug data file for this which has the following information:

 //  Program purpose:   
//      1) Program reads each student's names followed by their test score from 
//            a text file "T3DebugData.txt"   
//      2) Program should output each student's name followed by test scores 
//            and relevant grade to a file.
//      3) Program should also find and print the highest test score and  the 
//            names of all the students that got that score.
//      4) Program output file name is "T3DebugOut.txt".
//      5) The program must also include struct for the students name and tests
//      6) Assume 20 students max.

what IDE do you use? If its codeblocks they usually have theyre debugger below the editor.

for now here are the errors:
1. (in line 115) setw was not declared. u didn't add the header file called iomanip.
2. (in line 120) outfile was not declared. it should "outFile". c++ is case sensitive
3. (in line 112) listSize was not declared. in your function called printResult, you didnt declare listSize meaning you didnt declare what its suppose to be. is it int? double? does it have value? or none etc.

Dammned Programmer, I am using Xcode since I only have a mac to work on.

Thank you, I did realize these three errors but wasn't sure how to fix the setw error. Now I know.
Most troubling ones are the logical errors that I think are present here.
