    printing two dimensional array

    I have a matrix and I need to be able to print out all of its contents. Right now I have it such that const int size = 2;
    And then my matrix is matrix[size][size];

    It needs to work of course so that if I change the size it will still work properly. I know I need to do it using to for loops and two variable row and column. But I have been thinking about it for a couple hours and I can't come up with anything. Can anybody help?

    Wouldnt it be something as simple as:
    Code:
    for (int i = 0; i < size; ++i) {
    	for (int j = 0; j < size; ++j) {
    		// print matrix[i][j]
    	}
    	// print a break (e.g. newline) for next row of matrix
    }

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
