I need help with my C++ class ( we are using Microsoft Visual Studio 2008)?

long odoMonday;

long odoFriday;

double gallonsMonday;

double gallonsTuesday;

double gallonsWednesday;

double gallonsThursday;

double gallonsFriday;

// Ask for the starting odometer reading.

// Save the starting odometer reading into odoMonday

// Ask for the ending odometer reading.

// Save the ending odometer reading into odoFriday

// Ask for and save the gallons purchased for each day.

double total = // add all of the variables holding the gallons pre day.

double average = total / 5.0;

double mpg = (odoFriday - odoMonday) / total;

// Ouput all of these.

Good luck with it.

C++ is a superset of of C. You should be able to write C inside a C++ application. As an aside, you might want to find a nicer environment to learn in, as I'd been writing C++ professionally for 8 years before using Visual Studio and MFC. Its a nightmare and a perfect illustration of why Microsoft products are full of bugs and security flaws.

Just start with something, then build. Start by implementing one day. Once you get that working add the other days. Once thats good add a starting odometer reading.

Steps are key to good programming. On a small scale program like this you may be able to do it all at once, but what happens when you need to write a program with 10, 000 lines of code?

If you have the pseudocode what's the problem?
