Should I make sure to destroy SDL 2.0 objects (renderer, window, textures, etc.) before exiting the program?

Should I make sure to destroy SDL 2.0 objects (renderer, window, textures,
etc.) before exiting the program?

This tutorial on SDL 2.0 uses code that returns from main without first
destroying any of the resource pointers:
int main(int argc, char** argv){
if (SDL_Init(SDL_INIT_EVERYTHING) == -1){
std::cout << SDL_GetError() << std::endl;
return 1;
}
window = SDL_CreateWindow("Lesson 2", SDL_WINDOWPOS_CENTERED,
SDL_WINDOWPOS_CENTERED, SCREEN_WIDTH, SCREEN_HEIGHT,
SDL_WINDOW_SHOWN);
if (window == nullptr){
std::cout << SDL_GetError() << std::endl;
return 2; //this
}
renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED
| SDL_RENDERER_PRESENTVSYNC);
if (renderer == nullptr){
std::cout << SDL_GetError() << std::endl;
return 3; //and this too
}
Should I tell my terminate function to DestroyRenderer, DestroyWindow,
DestroyTexture, etc. before exiting?
