Thread: char problem

ok, i worked a while on this program and worked out all of the bugs myself except this one error i keep getting saying

error C2440: '=' : cannot convert from 'char [2]' to 'char'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast

why does it say that when it is only 1 letter i'm trying to put in the variable...and i even tried actually putting grade[1], and it didnt do a thing.

Code:

#include<iostream.h>

class StudentGrade
{
	private:
		int idNum;
		char name[20];
		int testScore;
		int possible;
		char grade;
	public:
		StudentGrade(const int id, const char lname[], const int score, const int possPoints);
		StudentGrade(const int id, const char lname[], const int score);
		void displayStudentGrade();
		void findGrade();
};

StudentGrade::StudentGrade(const int id, const char lname[], const int score, const int possPoints)
{
	idNum=id;
	findGrade();
	
}
StudentGrade::StudentGrade(const int id, const char lname[], const int score)
{
	idNum=100;
	findGrade();
}
void StudentGrade::displayStudentGrade()
{
	cout<<"Student #"<<idNum<<" "<<name<<" earned "<<testScore<<" out of "<<possible<<".  Letter grade is "<<grade<<endl;
};
void StudentGrade::findGrade()
{
	if(testScore/possible>=90)
		grade="A";
	else if(testScore/possible>=80 && testScore/possible<90)
		grade="B";
	else if(testScore/possible>=70 && testScore/possible<80)
		grade="C";
	else if(testScore/possible>=60 && testScore/possible<70)
		grade="D";
	else
		grade="F";
};
void main()

{

	StudentGrade a(111,"McDevitt",98);
	StudentGrade b(222,"Zimmerman",85);
	StudentGrade c(333,"Feuger",70);
	StudentGrade d(444,"Tripp",69);
	StudentGrade f(555,"Baier",50);
	StudentGrade a1(666,"Pfeiffer",237,250);
	StudentGrade b1(777,"Faris",245,300);
	StudentGrade c1(888,"Heisler",700,1000);
	StudentGrade d1(999,"Cassidy",63,105);
	StudentGrade f1(1000,"Freund",2,200);

	a.displayStudentGrade();
	b.displayStudentGrade();
	c.displayStudentGrade();
	d.displayStudentGrade();
	f.displayStudentGrade();
	a1.displayStudentGrade();
	b1.displayStudentGrade();
	c1.displayStudentGrade();
	d1.displayStudentGrade();
	f1.displayStudentGrade();
