SDL_BlitSurface doesn't draw to screen - c++

Question

I'm trying to simply create a window and blit an image to the screen but for some reason the image is not showing up and the screen remains white. I've been using lazyfoo's tutorial for reference in order to figure this out. I posted all my code below, hopefully it's readable enough. Help would be appreciated as I've been stuck on this for an hour or two, thank you.
#include <SDL.h>
#include <SDL_audio.h>
#include <cstdio>
#include <iostream>
#include <Windows.h>
// creates Load_surface function
SDL_Surface *loadSurface(std::string path) {
SDL_Surface *loadedSurface = SDL_LoadBMP(path.c_str());
if (loadedSurface == NULL) {
printf("Unable to load image %s! SDL Error: %s\n", path.c_str(),
SDL_GetError());
}
return loadedSurface;
}
int main(int argc, char ** argv)
{
// pointer variable for window
SDL_Window *window;
SDL_Surface *surface = NULL;
SDL_Surface *media =
loadSurface("C:\\Users\\nickl\\Desktop\\buttonpressed.bmp");
// initialize and test for failure
if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_AUDIO) == -1) {
return 1;
}
// create the window
window = SDL_CreateWindow(
"Ice Cream Boys Software",
48,
48,
640,
480,
SDL_WINDOW_OPENGL
);
// safety check, see if window was created, otherwise throw an error
if (window = NULL) {
printf("Could not create window: %s", SDL_GetError());
return 1;
}
else {
OutputDebugString(TEXT("Surface loaded.\n"));
surface = SDL_GetWindowSurface(window);
}
SDL_BlitSurface(media, NULL, surface, NULL);
SDL_UpdateWindowSurface(window);
/* ************************************** loop **************************** */
// bool to keep window open and event handler
bool quit = false;
SDL_Event e;
// loop to keep window open
while (!quit) {
while (SDL_PollEvent(&e) != 0) {
if (e.type == SDL_QUIT) {
quit = true;
}
else if (e.type == SDL_KEYDOWN) {
OutputDebugString(TEXT("My output string.\n"));
}
}
}
/* ************************************************************************** */
// close and destroy window
SDL_DestroyWindow(window);
// quit
SDL_Quit();
return 0;
}
