Menu driven program for system control using C++

Prerequisite: Switch-case in C/C++

Problem Statement:
Write a menu-driven program to control your system such as shutdown, restart, log off, manual shutdown settings, abort the shutdown, and exit, using Switch-case.

Approach: The idea is to use system() in C. This function is used to invoke operating system commands from the C++ program. 
In this program to use some system commands listed below:

1. Shutdown: To shutdown system, use system() function and command shutdown with option s as:

   system("C:\\WINDOWS\\System32\\shutdown/s")

2. Restart: To restart system, use system() function and command shutdown with option r as:

   system("C:\\WINDOWS\\System32\\shutdown/r")

3. Log off: To logoff system, use system() function and command shutdown with option l as:

   system("C:\\WINDOWS\\System32\\shutdown/l")

4. Manual Shutdown: To manual shutdown system, use system() function and command shutdown with option i as:

   system("C:\\WINDOWS\\System32\\shutdown/i")

5. Abort the Shutdown: To abort the shutdown system, use system() function and command shutdown with option a as:

   system("C:\\WINDOWS\\System32\\shutdown/a")

Below implementation of the above system function and commands:

    scanf("%d", &choice);

    switch (choice) {

    case 2:

    case 6:

        printf("\n Exiting... \n\n");
        printf("Exiting in 3 seconds...\n");
        Sleep(3000);

    default:

        printMenu();

}

// Function to print all the menus

    // background and white foreground

    // Create Menu

           "______________________________\xB2\n");

    // Function call for select options
    selectMenu();

// Driver Code
int main()

    // Function Call

    return 0;
