Sprite collision to window?

Question

C++ / C#

How to make a character collide to the window (to push away from the window)?
Can you show the code?

I won’t help with the code itself (I don’t know c++), but I’ll explain how it should happen using pascal as an example -
// checking for a collision with the right side
if (x >= [window border coordinates]-[player width]) then x:=[coordinates window borders];
//check for left side collision
if (x <= 0[<-- window coordinate]) then x:=0;
// check for collision with top side
if (x >= 0[<-- window coordinates]) then x:=0;
//check for collision with bottom side
if (x >= [window border coordinates]-[player width]) then x:=[window border coordinates];
