VISUALSTUDIO:- I need little assistant with my codes, I have done every steps apart from the steps typed in CAPITAL.

Using c++ creat a bouncing green circle in a yellow window of 700x700 pixels size using shaders. You can use shades of the given colors below.

-Show the green circle in a 700x700 yellow window.

-The circle starts moving in an animation diagonally and bouncing back from the sides.

-There should be a red horizontal line of 1/4 width in the middle of the screen.

=THE CIRLE SHOULD ONLY TURN RED WHEN IT CROSSES THE RED HORIZONTAL LINE AND YOU SHOULD BE ABLE TO MOVE THE RED HORIZONTAL LINE UP and DOWN WITH THE USE OF THE KEYBOARD.

PLEASE Could u kindly check my code and edit it ONLY to the steps TYPED in capital.

MY CODES:
