Lab 7
Spring Break is approaching fast. You have decided to drive to West Palm Beach to spend the week with
your friends. As a part of your planning, you need to determine how long it will take you to get there and
how much you will need to spend on gas. The distance between Columbia and West Palm Beach is
approximately 575 miles and the current price of gas is $2.89 per gallon.
Declare four floating point variable called Cost, Time, Speed, and MPG
float Cost, Time, Speed, MPG;
Write an input statement for Speed and then (at the prompt) enter the value representing the average
speed at which you drive on interstate highways
cin >> Speed;
Write an input statement for MPG and then (at the prompt) enter the value representing the average
highway gas mileage for your car
Calculate the total amount of time required for your trip
Time = 575/Speed;
Calculate the cost of gas for your trip
Cost = (575/MPG)*2.89;
Output the total trip time and gas cost values
cout << “Your trip will take: ” << Time << “ hrs” << endl;
cout << “The total cost of gas for your trip is: $” << Cost << endl;
Using the program mode
Open Notepad
The first line must be a comment statement. Include your name in the comment. Look at the tutorial for
this.
Go to the file menu and select “save as.” In the top dropdown box select your H drive. Save your file
directly onto the H drive, do not put it inside any folders. Choose “all files” in the type dropdown
menu (just like we did to save html files.) Finally, give your file a .ch extension (just like we gave our
html files a .html extension.) Click save. Remember to save your file often.
Type the include statement that is needed to facilitate input/output capabilities. Look at the tutorial for
this.
The beginning of your code starts with the following statement: main ( ) {
Enter your code after the opening curly bracket. Your code should contain the statements to do the
following. Remember to close each line of code below with a semicolon.
oDeclare four floating point variable called Cost, Time, Speed, and MPG.
oOutput a short phrase asking for the user’s average driving speed on interstate highways.
