Thread: NOOB: Need a little help opening file and manipulating data

I'm getting really weird numbers. I think I have some sort of overflow or data still left in memory. I'm not sure how to fix this.

Thanks in advance.

.txt file:

Barney Jones 95 83 92 85 87 85 29
Sandra King 99 97 92 91 92 95 32
Josh Harding 0 0 0 0 31 37 30

That's probably why I'm getting funky numbers. So how do I declare them in the code AND make sure that they are read in sequence?

I think I may have solved part of it... Thanks for the heads up on the int and the names...

Code:

//This program averages grades and determines pass/fail.
//It also determines pass/fail through attendance

#include <iostream>
#include <fstream>
#include <iomanip>
using namespace std;

int main()
{
	

	ifstream inFile;
	
	char first[13], last[13];
	int a1, a2, a3, a4, t1, t2, attendance;
	double test, assignment, average;

	inFile.open("d:\\grades.txt");				//Using d: because I have no a: drive
	cout <<"Reading Data from file.\n\n"<<endl;
	
	//Average first set of grades
	inFile >> first;
	inFile >> last;
	inFile >> a1;
	inFile >> a2;
	inFile >> a3;
	inFile >> a4;
	inFile >> t1;
	inFile >> t2;
	inFile >> attendance;
	assignment = (a1+a2+a3+a4)/4;
	test = (t1+t2)/2;
	average = (assignment + test)/2;
	cout <<first<<" "<<last<<" average is: "<<average<<endl;
	if (average < 60)
		cout<<"\nFAILED: grade requirements.\n";
	if (average >= 60)
		cout<<"\nPASS: grade requirements.\n";
	if (attendance < 30)
		cout<<"\nFAILED: poor attendance.\n";
	if (attendance >=30)
		cout<<"\nPASS: attendance requirement.\n";
	cout<<setfill('-')<<setw(80)<<"-"<<endl;

	


//Close the file
	inFile.close();
	cout<<"\nDone.\n\n";
	return 0;
}

a little lost on theis part of the code... what does the:

' '

do? does this give it a maximum of 15, but stop at the first space?

It uses a space as the delimiter instead of the newline character.
