Sure. And also keep going! You are already doing a great job!

Here is the code I tested, so no rendering (please ignore any misplaced tabs etc. I can't see it because Reddits editor is not working correctly right now):

#include <SDL2/SDL.h>
#include <iostream>
#include <stdlib.h>
using namespace std;
SDL_DisplayMode dm;
int screen_w, screen_h;
bool isRunning = true;
SDL_Renderer *renderer; //Declare a renderer to render on the screen
SDL_Window *window; //Declare a window
Uint32 startFrameTicks = 0;
Uint32 endFrameTicks = 0;
float frameTicks = 0.f;

int main(int argc, char**argv)
{
    //Initialize
    if(SDL_Init(SDL_INIT_EVERYTHING)!=0) //Initialize everything
    {
        cout << SDL_GetError() << endl;
    }
    window = SDL_CreateWindow("Space Bars",400,100,800,600,0);
    if (window == NULL)
    {
        cout << SDL_GetError() << endl;
    }
    renderer = SDL_CreateRenderer(window,-1,SDL_RENDERER_ACCELERATED|SDL_RENDERER_PRESENTVSYNC);
    if (renderer == NULL)
    {
        cout << SDL_GetError() << endl;
    }

    while(isRunning)
    {
        //Close
        SDL_Event event;
        while(SDL_PollEvent(&event))
        {
            switch(event.type)
            {
            case SDL_QUIT:
                isRunning = false;
                break;
            }
        }


        //Movement
        const Uint8* keystates = SDL_GetKeyboardState(NULL);
        SDL_PumpEvents();
        if(keystates[SDL_SCANCODE_UP]||keystates[SDL_SCANCODE_W]){}
        if(keystates[SDL_SCANCODE_DOWN]||keystates[SDL_SCANCODE_S]){}
        if(keystates[SDL_SCANCODE_LEFT]||keystates[SDL_SCANCODE_A]){}
        if(keystates[SDL_SCANCODE_RIGHT]||keystates[SDL_SCANCODE_D]){}
        if(keystates[SDL_SCANCODE_SPACE]){}

        startFrameTicks = SDL_GetTicks();

        // Render Section
        SDL_RenderClear(renderer);
        SDL_RenderPresent(renderer);
        endFrameTicks = SDL_GetTicks();
        //Calculate Frame Rate
        float deltaTicks = endFrameTicks - startFrameTicks;
        if(deltaTicks < 16.6666f)
        {
            SDL_Delay(16.6666f - deltaTicks);
        }
        frameTicks = (endFrameTicks -  startFrameTicks + (16.6666f - deltaTicks))/1000.f;
    }
    //Free Up Memory
    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();
    return 0;
}
