When I call the following section of code, I get to the section to enter an integer for enter number of grades to drop and my program crashes.

void Course::enterGCInfo(int num)
{
	GradeCat tempGC;
	string tempStr = "";
	cout << "Enter Grade Category Name: ";
	cin >> tempStr;
	tempGC.setGCName(tempStr);
	double tempDbl = 0.0;
	cout << "Enter Grade Percentage: ";
	cin >> tempDbl;
	tempGC.setGCPerc(tempDbl);
	int tempInt = 0;
	cout << "Enter Number of Grades To Drop: ";
	cin >> tempInt;
	tempGC.setNumToDrop(tempInt);
	setGradeCat(num,tempGC);
	refresh();
}

This is the error message:

Unhandled exception at 0x004149eb in Grade Tracker.exe: 0xC0000005: Access violation reading location 0x3343f1c8.

I'm using Visual Studio 2010 Express - Start Debugging. When it reaches this error it takes me to following code in file xstring

	bool _Grow(size_type _Newsize,
		bool _Trim = false)
		{	// ensure buffer is big enough, trim to size if _Trim is true
		if (max_size() < _Newsize)
			_Xlen();	// result too long
		if (this->_Myres < _Newsize)
			_Copy(_Newsize, this->_Mysize);	// reallocate to grow
		else if (_Trim && _Newsize < this->_BUF_SIZE)
			_Tidy(true,	// copy and deallocate if trimming to small string
				_Newsize < this->_Mysize ? _Newsize : this->_Mysize);
		else if (_Newsize == 0)
			_Eos(0);	// new size is zero, just null terminate
		return (0 < _Newsize);	// return true only if more work to do
		}

The cursor stops next to this line:

if (this->_Myres < _Newsize)

The function calls dealing with that Integer input

setNumToDrop

void GradeCat::setNumToDrop(int num)
{
	numToDrop = num;
}

setGradeCat

void Course::setGradeCat(int num,GradeCat tempGC)
{
	GCs[num] = tempGC;
}

GCs is an array of GradeCat objects

refresh

void Course::refresh()
{
	calcGrade();
	calcTotalPerc();
	sortGradeCats();
}

why all = faknob? i want know! :(

umm, you'll have to put that into so easier language to me to understand.

Anyway, I figured out my problem, I knew it would be something stupid. I was not sending a proper value to the function, so that improper value was being used to insert an object into an array. DOH!

i see how they = st00pid but they all die... :(

man listen i want to start creating my own games in C++ using directx9. but i'm right at the start! i'm barely at chapter 4 from Thinking in C++. and i have some questions about what i learned. so take this as an example

void (*funcptr)();
//so this is a pointer to a function which takes no arguments and returns void

void* funcptr2();
//a function which returns a pointer to void

void* (*(*fp1)(int))[10];
//fp1 is a pointer to a function which takes an int an returns a pointer to an array of 10 pointers to void

float (*(*fp2)(int,int,float))(int);
//fp2 is a pointer to a function which takes 3 arguments and returns a pointer to a function which takes an int and returns float

i can read most of these expressions using the middle-right-left-right-etc method described in the book. but i'm not sure i can use this stuff - it seems too complicated. so if i take up game programming would i bump often into such things?

PS i now mother not home but she come late ok?
