You have following declarations:


// Constants
#define MAX_BUTTONS 256
#define MAX_TEXT_LEN 256
#define BUTTON_WIDTH 100
#define BUTTON_HEIGHT 50

// Structures
typedef struct {
    int x;
    int y;
    COLORREF color;
} WINDOW;

typedef struct {
    int x;
    int y;
    COLORREF color;
    COLORREF highlight_color;
    char name[MAX_TEXT_LEN];
} BUTTON;

typedef struct {
    WINDOW window;
    BUTTON buttons[MAX_BUTTONS];
    int num_buttons;
} MENU;

// Global variables
HINSTANCE hInst;
HWND hWnd;
MENU menu;

// Helper functions
void ParseMenuFile(char* menu_file_name); // +
int GetButtonUnderCursor(int x, int y); //
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam);
void DrawWindow(HDC hdc, WINDOW* window); // +
void DrawButton(HDC hdc, BUTTON* button, BOOL highlighted); // +```
Now, write the following functions:
1. SystemOpen/SystemClose - functions for opening and closing the system. They must be called once during the operation of the program.
2. SystemInitialize(menu file name) - system initialization function. It can be called several times during the program operation, for example, if the menu needs to be unloaded from memory before continuing the program operation. The name of the file containing information about the structure and composition of the menu is passed as a parameter. The approximate file format is described below.
3. SystemRelease - the function is paired to SystemInitialize and is called when it is necessary to unload the system from memory.
4. SystemUpdate - it is assumed that the menu screen is rendered inside this function, as well as user interaction. The result of the function is the name of the selected button (the button that was selected by the user at the time of pressing the Enter key).

# trail sand You have following declarations: ```#include <windows.h> // Constants #define M...

Here's the implementation for the requested functions:

// System functions

// Function to be called when opening the system
void SystemOpen() {
    // Initialize the system
    // It could contain things like loading necessary DLLs or initializing global variables
}

// Function to be called when closing the system
void SystemClose() {
    // Clean up the system
    // It could contain things like releasing allocated memory or unloading DLLs
}

// System Initialization function
void SystemInitialize(char *menu_file_name) {
    // Load the menu structure and composition from the menu file
    ParseMenuFile(menu_file_name);

    // Initialize other necessary parts of the system
}

// System Release function
void SystemRelease() {
    // Release any allocated resources when unloading the system from memory
}

// System Update function
char *SystemUpdate() {
    MSG msg;
    BOOL bRet;

    while ((bRet = GetMessage(&msg, NULL, 0, 0)) != 0) {
        if (bRet == -1) {
            // Handle the error and possibly exit
        } else {
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }

        // Get cursor position
        POINT cursor_pos;
        GetCursorPos(&cursor_pos);

        // Get the button which is currently under the cursor
        int button_index = GetButtonUnderCursor(cursor_pos.x, cursor_pos.y);

        // If the enter key is pressed, return the button name
        if (GetAsyncKeyState(VK_RETURN) & 0x8000) {
            if (button_index != -1) {
                return menu.buttons[button_index].name;
            }
        }
    }

    return NULL;
}

These functions should be added to your existing code. Note that the actual resource allocation and cleanup within the SystemOpen and SystemClose functions, as well as the specifics of rendering the menu and handling user interaction, will depend on the details of your implementation.

Write a simple menu system using WinAPI, in the C programming language. Use all previsiously listed code. It is assumed that the menu consists of windows and buttons. It is assumed that interaction with the user is carried out using the buttons (up, down, Enter). The system should provide the user with the following functions:

  1. SystemOpen/SystemClose - functions for opening and closing the system. They must be called once during the operation of the program.
  2. SystemInitialize(menu file name) - system initialization function. It can be called several times during the program operation, for example, if the menu needs to be unloaded from memory before continuing the program operation. The name of the file containing information about the structure and composition of the menu is passed as a parameter. The approximate file format is described below.
  3. SystemRelease - the function is paired to SystemInitialize and is called when it is necessary to unload the system from memory.
  4. SystemUpdate - it is assumed that the menu screen is rendered inside this function, as well as user interaction. The result of the function is the name of the selected button (the button that was selected by the user at the time of pressing the Enter key).
    The format of the menu file can be as follows:
    MenuBegin
    WindowBegin
    Position=(x,y)
    Color=
    WindowEnd
    ButtonBegin
    Position=(x,y)
    Color=
    HiglightColor=
    Name=
    ButtonEnd
    MenuEnd
