{

float hours;

cout <<"Enter number of hours a car parked at the airport: "; // prompt the user to enter hours.

cin >> hours ; // strong the hours

if (hours > = 0 && hours < =3 ) // if 0 < = h < = 3

cout << "Parking fee: 5"; //printing parking fee is 5.

else if (hours > 3 && hours < = 9)//if 3 < h < = 9

cout<<"Parking fee: "<<6*int(hours);//converting float value to int the multiplying with 6 then printing fee.

else//if 9 < h < = 24

cout<< "Parking fee: 60";// printing parking fee 60.

Use the Windows ________ to check on a nonresponsive program. Select one: A. Backup utility B. Task Manager C. System Restore D.

Nitella [24]

The answer is task manager. You can access it by pressing the Windows key and searching "task manager". You can also press ctrl+alt+delete or ctrl+shift+esc to access it.

Taskanager will show you all the applications currently running and how many resources they are using. If a task is unresponsive, it can be force closed from task manager.
