SDL2 understanding help

[Corak55]

Dear Community,

I writing a turn based strategy game and have understanding difficulties how I can express text and graphics using SDL2.

For the start I only want to display several characters and numbers, have a button "next turn" that clears the screen and displays the altered variables again.

However, with SDL2 for now I managed only to post 1 image or 1 ttf-rendered text message at a time. Maybe I missed some of the basics of SDL2. Is there anyone out there who can help me out?

Kind regards,
