Bool Functions???

[DeepThoughtEli]

I am attempting to write a program that will allow someone to play the matching game. The problem I have though is using a bool function. Somehow I am supposed to fill a a char 2d array with all stars and then as the player chooses cards to flip over and they match then they will stay. The char array is to be a 4x4 array filled with *'s and then when the correct pair of cards are chosen then that pair of numbers will continue to show.

How would i write a bool function to do this?

below is a code a friend helped me type but I'm not sure if it is right...

const int SIZE = 4;


int main ()
{
	char answer;
	int X1, Y1, X2, Y2;
	int GameArray[SIZE][SIZE] = { { 1, 2, 3, 4},
								  { 5, 6, 7, 8},
								  { 1, 2, 3, 4},
								  { 5, 6, 7, 8} };

	
	bool isFaceUp[SIZE][SIZE];	// declaration for the number of rows and columns and the array size of 20 rows and 15 columns as a max
	
	for(int i = 0; i < SIZE; i++)			//set all values of isFaceUp to false so all cards are face down
	{
		for(int a = 0; a <SIZE; a++)
		{
			isFaceUp[i][a] = false;
		}
	}

That looks good so far.
What do you want the 'bool function' to do?
Do you want it to return true if a match is made and false if not?
Assuming that you have gotten two row and column choices from the user then perhaps this will do:

// GameArray is passed to this function along with the users choices
bool isMatch( int GA[][SIZE], int row1, int col1, int row2, int col2 )
{
    return GA[row1][col1] == GA[row2][col2];
}

or do you need it to modify the (as yet non-existent) character array too?

Basically I was told by my professor that I need a bool function. Im told that I need one array for all of the numbers and then randomize those numbers in a 2D array. That array is a 4x4 that involeves the number 1-8. Then im told that i need another array 4x4 that is filled with stars (*) and will display the number if the player chooses correctly. The player will chose the coordinates when shown the table of all *'s and the number 1-4 across the top and the left side of the table.

I have another post on here that has the majority of my code which has not changed much. If you could look at that one too that would be very helpful.
