gradually until it is all white, and then changes its color gradually back to black. Only stop when the user

presses ESCAPE.

Hint: $(0,0,0)$ is the color black while $(255,255,255)$ is the color white.

Lab$7$B: Create a Rxgame screen which is $600600,$ and then draw $4$ red squares, each at a corner of the

screen, and one red square at the exact center of the screen. All squares must be $6060.$ The game

must run until the user presses ESCAPE. $($Remember to account for the Surface's width and height!$).$

Lab$7$C: Create $2$ Rects that are $100100,$ one with starting coordinates at the top left of the screen and

the other one with starting coordinates at the bottom left of the screen. Create $2$ Surfaces, one green and

one Blue, also $100100.$ Use the two Rects to blit the two Surfaces onto the Display.

Using move$(),$ move the two Rects across the screen and, when they reach the border, have them return

to where they started, repeating the cycle. The Rects should move at a speed of $5$ pixels at a time. The

Display must be $1000500.$ Only stop when the user presses ESCAPE.

Hint: You probably want to keep track of what direction the Rects are moving.
