Thread: pointer of array of class

hello!

i have problem with program i made:
the program should define a pointer to pointer which points to dynamic array of Grade (class i made).
i increase the size of the array in function. so i made a new pointer to pointer which point to array of Grade (the class i made). i transferred the old array to new one, and finaly, before i going out of the function, i shoud transfer it's address to the first pointer i made:

Code:

{
int students=1;
	
	Grade ** numGrades=new Grade * [students];
	numGrades[0]=new Grade;
	assert(numGrades!=0);
	AddGrade(numGrades,students);	
}
void AddGrade(Grade ** _numGrades,int& _students)
{
	_students++;
	Grade ** gradeTemp=new Grade * [_students];
	for(int i=0;i<_students-1;i++)
		gradeTemp[i]=_numGrades[i];
	gradeTemp[i]=new Grade;

}

how can i transfer the address of "gradeTemp" to "numGrades"?

thank you,
Moshiko

or just call AddGrade with the adress of numGrades and use it in AddGrade as a pointer of a pointer of a pointer^^

Code:

	AddGrade(numGrades,students);	

void AddGrade(Grade ** &_numGrades,int& _students)
{
.
.
.
}

but i can't define it like this, it write an error. so how can i define _numGrade as a reference of numGrades?
