Dynamic Array Issue

[TaytayB]

I've written functions to increase, and decrease, my array. It works fine when increasing, however, when I go to shrink it, it crashes :(

void Register::GrowArray()//Similar to class provided code
{
	static Sale* temp;
	temp = new Sale[MaxArray+ARRAYSIZE];
		for(int i = 0; i < MaxArray; i++)//Copies Data
			temp[i] = saleArray[i];
	delete [] saleArray; 
	saleArray = temp;
	cout << "Increased register size to: " << MaxArray+ARRAYSIZE << endl;
}
void Register::ShrinkArray()
{
	static Sale* temp;
	temp = new Sale[MaxArray-ARRAYSIZE];
		for(int i = 0; i < MaxArray; i++)//Copies Data
			temp[i]= saleArray[i];
	delete [] saleArray;
	saleArray = temp;
	cout << "Decreased register size to: " << MaxArray-ARRAYSIZE << endl;
}

Does anyone have any Idea what may be wrong?

I'm gonna assume it has to do with temp = new Sale[MaxArray-ARRAYSIZE];
What is MaxArray and what is ARRAYSIZE?

In your for loop in the ShrinkArray() method, i is increasing to 'MaxArray' where your temp array only has 'MaxArray - ARRAYSIZE' size. So you are attempting to access out of bounds of temp when you do:

temp[i] = saleArray[i];

So just change your for loop to:

for(int i = 0; i < MaxArray - ARRAYSIZE; i++)//Copies Data
			temp[i]= saleArray[i];
