C++ SDL2

Hello everyone, I need to create the first draft of the AT-Robots game. I need to create a gray arena with black borders and with columns and rows on the right side which will containt three rectangles per each row with the information about the robots, like: health, name and color. For now I just need to design the arena with columns and rows with some random colors, names and health percentage. Here is a sample of how it should look like and here is my code so far.

const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;
int main(int argc, char* argv[])
{
    SDL_Window* window = NULL;
    SDL_Renderer* renderer = NULL;
    SDL_Surface* screenSurface = NULL;

    if (SDL_Init(SDL_INIT_VIDEO) < 0) {
        printf(\"Could not initialize SDL. SDL_Error: %s\ \",SDL_GetError());
    }
    else
   {
       window = SDL_CreateWindow(\"SDL Test\",SDL_WINDOWPOS_UNDEFINED,SDL_WINDOWPOS_UNDEFINED,SCREEN_WIDTH,SCREEN_HEIGHT,SDL_WINDOW_SHOWN);
       if (window==NULL) {
           printf(\"Cannot create window. SDL_Error: %s\ \",SDL_GetError());
       }
       else {
           SDL_Rect arect;
           screenSurface=SDL_GetWindowSurface(window);
           SDL_FillRect(screenSurface,NULL,SDL_MapRGB(screenSurface->format,0,0,0));
           arect.x=14; arect.y=14; arect.w=SCREEN_WIDTH-28; arect.h=SCREEN_HEIGHT-18;
           SDL_FillRect(screenSurface,&arect,SDL_MapRGB(screenSurface->format,128,128,128));
           SDL_RenderClear(renderer);

            SDL_SetRenderDrawColor(renderer, 66, 134, 244, SDL_ALPHA_OPAQUE);
            SDL_RenderDrawLine(renderer, 320, 200, 300, 240);
            SDL_RenderDrawLine(renderer, 300, 240, 340, 240);
            SDL_RenderDrawLine(renderer, 340, 240, 320, 200);
            SDL_RenderPresent(renderer);

           SDL_UpdateWindowSurface(window);
           SDL_Delay(3000);
       }

   }
   SDL_DestroyWindow(window);
    SDL_Quit();
    return 0;
}
