I can't seem to get it working properly. Here's what I have thus far.
#include <string>
#include <iostream>

char grade[2]; //to hold the students letter
public:
static int numStudents;
static int innerCount;
void ReadRecord();
void CalculateGrade();
void WriteRecord();
void ReportSummary();
};

int Student_t::innerCount=0;

//Students information and exam grades and store in student_t

cin >> average;
cin >> average;
numStudents++;
}
//CalculateGrade's function is to determine the letter grade
//and average grade for the student
void Student_t::CalculateGrade()
{
double avg=0;
avg = (exam1*.2)+(exam2*.2)+(homeworkavg*.35)+(.25*average);

if(avg >= 90)strcpy(grade,"A"); //assign letter grade
else if(avg >= 80)strcpy(grade,"B");
else if(avg >= 70)strcpy(grade,"C");
else if(avg >= 60)strcpy(grade,"D");

}
//WriteRecord's function is to display all the gathered information on
//the screen after the averages and letter grades have been assigned
void Student_t::WriteRecord()
{

}

}
return 0;
}
