Write a 32-bit program that displays a series of six different characters ("A" through "F") in all possible combinations of foreground and background colors (16 x16 = 256). The result will be a grid that is 16 columns wide by 16 rows high.
Begin by displaying the letter "A" in all colors. Then pause the screen for 1 second, and replace the output with a display of the letter "B" in all colors. Pause again, then use the letter "C", and so forth, through the letter "F".
The colors are numbered from 0 to 15, so you can use a nested loop to generate all possible combinations. Read pages 539-541 to learn about video text colors.
You can write this program in 32-bit mode by calling the following procedures from the Irvine32 library: Clrscr, SetTextColor, Gotoxy (or Crlf), WriteChar, Delay.
