Yes, and use x to check whether it is time to go onto the next row.

Yes. Or you could write it as a function:

        print_e(int height, int width) {
                /* function here */
        }

and write a test driver file, for example:

        int main() {
                print_e(6,4);
                print_e(1, 10);
                /* etc */
        }

Yes, you will have to recompile the test driver to add or change tests,
but it still illustrates the concepts nicely, and it is good to write
tests for your code :-)
