Help Needed: Nested "for" loops reading data from input file

[forbesthebrit]

Hi, I am having issues with my code that reads data from an input file, and outputs it to an output file in a nice ordered manner. It reads how many students (3-5)and for each student it is supposed to read a Student's personal info, and 5 grades for 3 different courses and calculated the final grades for each course. The problem is that my loop is:
A. Running too many times for what it should be doing
B. Only reading the first students data for each loop, and only the first set of grades

My code looks like this:

  
#include <iostream>
#include <iomanip>
#include <fstream>
#include <cstring>

using namespace std;

int main()
{
	//Declaring the variables.

	int studentNumber;   
	string name;         
	int age;             
	string address;      
	int years;           
	string tel;          
	string social;      
	string courseNum;    //For storing the course number.
	double test1;        //For storing the grade for test 1.
	double test2;        //For storing the grade for test 2.
	double test3;        //For storing the grade for test 3.
	double test4;        //For storing the grade for test 4.
	double exam;         //For storing grade for the final exam.
	double finalGrade;   //For storing the calculated final grade for the class.
	char grade;          //For storing the calculated letter grade for the class.

	const double test1Percentage = .10;     
	const double test23Percentage = .15;    
    const double test4Percentage = .20;     
	const double examPercentage = .40;      

	
	cout << "Please enter the number of students: ";
	cin >> studentNumber;

	
    ifstream fin;
    ofstream fout;

    fin.open("Project3_A04371627_Input.txt");
    fout.open("Project3_A04371627_Output.txt");


	//Informing the user
	cout << "Reading the data files" << endl;

	for (int a = 1; a <= studentNumber; a++)
    {
        getline(fin,name);      //Reading the name
        fin >> age;             //Reading the age
        fin.ignore ();          //Ignore between fin and getline
        getline(fin,address);   //Reading the address
        fin >> years;           //Reading the years
        fin.ignore ();          //Ignore between fin and getline
        getline(fin,tel);       //Reading the telephone number
        getline(fin,social);    //Reading the social number

My input file looks like this:

John Doe

1234 Right drive, Yellowtown, TX 73452

[phone]
123-45-6789
CS1428

87.4
92.1
CS3002
95.4
92.1
87.4
78.6
77.5

With 3 more students and their course data just below the last grade above

and my output file looks like this:

Student Grade Sheet
Name of Student: John Doe
Age: 24
Address: 1234 Right drive, Yellowtown, TX 73452
Number of years at Texas State: 1
Telephone Number: [phone]
Student Soc. Security #: 123-45-6789
Course Number: CS1428

Test #1: 80.9
Test #2: 90.2
Test #3: 98.5
Test #4: 89.8
Final Exam: 97.7
Numerical Grade in CS1428: 93.4
Letter Grade in CS1428: A

Test #1: 0.0
Test #2: 90.2
Test #3: 98.5
Test #4: 89.8
Final Exam: 97.7
Numerical Grade in CS1428: 85.3
Letter Grade in CS1428: B

And it just loops the same data in the second paragraph above 15 times before repeating the SAME student data as the first student and all the same grade another 15 times twice.
Any help with what i did wrong would be mucho appreciated

Remove the loop on line 81. You're reading already the five value. With this loop you're doing that five times which failes (the stream goes into an error state). You get always the same values then.

[tipaye]

You have a spurious loop in line 81 "for (int c = 1; c <=5; c++)", comment out or delete that line.
You forgot your "fin.ignore();" after "fin >> exam;" on line 87
