yes I programmed Hello World
but how make games in c++
book tutorial serves
C++ does not have any functionality for rendering graphics in its standard library, you will need to use whatever APIs your target platform provide (or a higher level cross platform library such as SDL or SFML) for that.
At the most basic level a game consist of a loop that:
1. checks for user input.
2. Updates the game state
3. Draws a representation of the game state to the screen.
I'd recommend taking a look at SDL or SFML (both work on all major desktop operating systems and are reasonably easy to use)
