Help with Access Violation Writing Location C++

[FaiL___]

I am getting an access violation writing location error when trying to run this line of code:

directions[keyCount] = direction;

This is where I am declaring the array:

int directions[1600] = { 0 };

And this is the rest of the portion of code I am trying to run:

for (int count = 0; count < 4; count++)
		{
			if (room.direction[count] == DIRECTION_LOCKED)
			{
				key = findKey(count);
				if (key == 0)
				{
					unlocked_direction = count;
					correctKey = bruteForce(count);

					keys[keyCount] = correctKey;
					floorNum = room.name[0];
					floorNumInt = floorNum - '0';
					floors[keyCount] = floorNumInt;
					roomNum[0] = room.name[2];
					roomNum[1] = room.name[3];
					roomNumInt = atoi(roomNum);
					rooms[keyCount] = roomNumInt;
					directions[keyCount] = direction;
				}
				else
				{
					sentOption(count + 6, key);
				}
			}
			if (room.direction[count - 1] == DIRECTION_OPEN)
			{
				if (count == unlocked_direction)
				{
					keyCount++;
				}
			}
		}

Thanks in advance, quote me if you have any questions.

Where did you initially declare the value of keyCount and what is the value?

[xentropa]

What environment are you running this code on?

 

Are you trying to declare an array with a variable assigned to its dimension?  Generally, you can't do that.

@FaiL___ There's not enough code to tell but the most likely scenario is 'keyCount' being out of range.

You can try adding a assert that checks if keyCount is in the range [ 0, 1600 )

Just add "Public" to the start of wherever it's declared. Trust me  it's that simple

Care to elaborate what a access modifier, that is used to perform compile time access checking, has to do with a runtime error ?

[AJTerminator]

Have you tried it? Also, it's not at compile time, it's just based on the access rights of the code, so if it's private, then it can only be accessed by that script and nothing else, but sometimes it messes up and denies all access rights. Just add to where the array is declared and make it public. Also, what compiler are you using? I'm assuming Visual Studio?

In C++, access is evaluated at compile time, perhaps you're confusing with some other language?
