Help with Student Grades program - Page 2

[Murtan]

One side note, when I was writing the test app, I had to set Num_Students after I read from the input file. My read from the input file looks like the following: (there is some debug still so I can see that it is doing something)

printf("main: reading grades.txt\n");
	ifstream infile("grades.txt");
	if (!infile.is_open())
		printf("main: Failed to open grades.txt\n");
	else{
		while(!infile.eof() && i < Num_grades){
			infile >> grades[i].ID;
			infile >> grades[i].q1;
			infile >> grades[i].q2;
			infile >> grades[i].e1;
			infile >> grades[i].e2;
			infile >> grades[i].assg1;
			infile >> grades[i].assg2;
			infile >> grades[i].assg3;
			if (! infile.eof()){
				cout << "main: grades[" << i << "].ID=" << grades[i].ID << endl;
				i++;
			}
		}
	}
	infile.close();
	Num_Students = i;

Please make any changes from the above that make sense to you.

We need to get your code compiled and running. If you want to work on it some, go ahead. When I first started working with your file, I commented out anything that had a compile error that I couldn't "just fix". Then I started running it and got the functionality that was implemented working. Then I started adding the functionality that I had commented out. (Its an iterative approach to development.)

If you get stuck:
Compile your file.
Post the entire file you just compiled in code=c++ tags
Post the entire error list from that compile in code tags

@singhraghav
1) Don't Hijack threads - Start your own (we much much prefer it)
2) After 13 posts you are expect to now how to use code tags
(read this)

Follow that advise and you will get some help.

Thanks,
Chris

sorry my mistake

[ddanbe]

You have a string variable declared as sortList and a method declared as sortList.
Decide what you want, there are systems who can detect this before you even compile things.

Hey, I actually figured out how to do the "sortList"t function. Sorry, to go though all the trouble of figuring out how to fix that messed up sortList function I had to rewrite it because it was causing to many problems. OK, this is the last problem I have with the program. This is the new program:

#include<iostream>
#include<fstream>
using namespace std;
//Struct students defines each element in the array.
struct students{
       int ID;
       int q1;
       int q2;
       int e1;
       int e2;
       int assg1;
       int assg2;
       int assg3;
       };
//searchList will search inside of the infile for a specific ID of a student and output all of their grades.
int searchList(students grades[], int Num_Students, int ID){
                    int index = 0;
                    bool found =false;
                    while (index < Num_Students && !found){
                          if (grades[index].ID == ID){
                                            found = true;
                                            cout << grades[index].q1;
                                            cout << grades[index].q2;
                                            cout << grades[index].e1;
                                            cout << grades[index].e2;
                                            cout << grades[index].assg1;
                                            cout << grades[index].assg2;
                                            cout << grades[index].assg3;
                                            break;
                          }
                          index++;
                    }
                    if( found )
                           return index;
                    else
                            return -1;
}

This is the error:`int main()':
error: expected primary-expression before "int"

The error is in the call to "sortList" in case 3. I tried removing the semicolon, int variable, and calling it like this "sortList(students grades, int size) it doesn't compile. Yet, I think it's something pretty simple. :icon_wink:

[Murtan]

You still have string sortList; in main() and it is masking the function you want to call.

You need to pass the number of students to sortlist
Change the call sortList(grades, int size); into sortList(grades, Num_Students);

[Passiongamer25]

Thanks, Murtan and ddanbe it finally compiles and works. Phew.

[Murtan]

Unless you've changed the code more than outlined...it compiles, but doesn't necessarily work.

Make sure you test it to ensure that it does what it is supposed to.

If you are happy, we are happy...
