Write a sketch to create the following countdown timer. You MUST use timer interrupts.  At startup, the serial monitor will display: "Enter an integer between 5 and 20: " and record the user’s input as N. If user enters an integer outside this range or a non-integer, the program will display "Try again: " and wait for user input, N.  At 1 second intervals, the serial monitor will display, N, N-1, … (e. g. 16, 15, 14, … ) down to 0, and then stop.  In the middle of a countdown (before it reaches 0), if the user types "Pause", the countdown will pause (e. g. at the value M). It will resume again (from M) only when the user types "Resume". If the user types "Pause" or "Resume" after a countdown is complete, the program will display "No countdown in progress".  At any time (during a countdown, after a countdown is complete, or in the paused state), if the user types "Restart", it will restart the countdown from N.

Your program will make use of long long int variables for all calculations. note: the use of long long int requires that you have c++11 support. you should have this automatically if you are using a newer version of visual studio. the support is there for gcc as well, but you may need the -std=c++11 or -std=c++0x compiler flag. you first need to read in the total number of seconds. there is no prompt for the read (that is, you just do the cin without using a cout to display a prompt). this is going to seem a little strange when you are running your program in your ide

This first part of the film shows the early history of motion pictures. how accurate do you think the portrayal of the early motion picture industry is? why? is historical accuracy important in films and theatre productions? explain. in the scene where don is going to the party (starting at time code 14: 51), we see a street scene as he first rides with cosmo and then with kathy. what aspects did the filmmaker include to make the scene look and feel like don, cosmo, and kathy are riding in a car on a street? think about elements such as scenery, sound, props, lighting, and so on. a "talkie" picture is shown starting around time code 21: 15. how does the audience in the film react to the "talkie"? what influence do audiences have on film and theatre performances? how do film and theatre actors influence audiences? in the musical scene with cosmo (starting at time code 27: 00), how does the actor use props? what is the result? do you think the use of props effectively fulfilled the artistic vision for this musical number? why or why not?
