C++ SDL2 window not opening - c++

Question

i coded this.
#include <iostream>
#include "SDL.h"
int main(int argc , char** args)
{
SDL_Init(SDL_INIT_EVERYTHING);
SDL_Window* win = SDL_CreateWindow("my window", 100, 100, 640, 480, SDL_WINDOW_SHOWN);
if (!win)
{
std :: cout << "Failed to create a window! Error: " << SDL_GetError() << "\n";
}
SDL_Surface* winSurface = SDL_GetWindowSurface(win);
SDL_UpdateWindowSurface(win);
SDL_FillRect(winSurface, NULL, SDL_MapRGB(winSurface->format, 255, 90, 120));
SDL_DestroyWindow(win);
win = NULL;
winSurface = NULL;
return 0;
}
when i compile it, it opens the window, and it immediately closes. But the console doesn't. Here is a screenshot of my console(maybe it could help solving the problem?)
Would there be any solution to get the Window to not close?

Would there be any solution to get the Window to not close?
Start up an event-handling loop and handle some events:
// g++ main.cpp `pkg-config --cflags --libs sdl2`
#include <SDL.h>
#include <iostream>
int main( int argc, char** argv )
{
SDL_Init(SDL_INIT_EVERYTHING);
SDL_Window* win = SDL_CreateWindow("my window", 100, 100, 640, 480, SDL_WINDOW_SHOWN);
if (!win)
{
std :: cout << "Failed to create a window! Error: " << SDL_GetError() << "\n";
}
SDL_Surface* winSurface = SDL_GetWindowSurface(win);
bool running = true;
while( running )
{
SDL_Event ev;
while( SDL_PollEvent( &ev ) )
{
if( ( SDL_QUIT == ev.type ) ||
( SDL_KEYDOWN == ev.type && SDL_SCANCODE_ESCAPE == ev.key.keysym.scancode ) )
{
running = false;
break;
}
}
SDL_FillRect(winSurface, NULL, SDL_MapRGB(winSurface->format, 255, 90, 120));
SDL_UpdateWindowSurface(win);
}
SDL_DestroyWindow(win);
SDL_Quit();
return 0;
}
