Computer Question 1: Write code that simulates a TV remote control. Use the menu command to display the numbers 3 through 9 as separate buttons. (Note that they don’t have to be in the same layout as on a remote control). Have a final menu item: “Turn TV off” The user will click a channel number (3 through 9). Then, keep repeating this process of displaying the menu and clicking a channel number until “Turn TV off” is clicked. At that point, use fprintf to display 1) the last channel the TV was on before it was shut off, and 2) How many times the channel was changed. changed=0; while (1) tv = menu( 'Choose Channel: ' , '3' , '4' , '5' , '6' , '7' , '8' , '9' , 'Turn TV Off' ); switch tv case 8 break ; otherwise channel=tv+2; changed=changed+1; end end fprintf( 'The final channel was %.0f, and it was changed %.0f times.\n' ,channel,changed); -0 if they are off by one with the number of times channel was changed, it’s ambiguous what that means -0 if they don’t use switch, they don’t have to -3 if they mess up fprintf, or have a small syntax error or two -3 if they mess up the “number of times channel changed” part
