    Question Please Help Me with this beginner C++ Program!

    Ok, I need help with this, Im just starting out and have no clue where to start...this is what I have to do....

    Write a program to ask the user for odometer readings before and after and gallons of gas used for each of three trips. Calculate the distance and miles per gallon for each trip. Display that information in a report like:

    Trip Report
    Trip Start End Distance Gallons MPG
    1 10078.9 10172.6 93.7 4.65 20.0
    2 10364.0 10687.5 323.5 14.90 21.7
    3 11538.3 11647.8 109.5 5.34 20.5

    Could someone please show me where I start? I have no clue how, as stated im a beginner.

    Simple, do TripStart Minus TripEnd millage as a values to get distances

    For Miles per gallon it's Miles/Gallons = MPG

    Setting up the displace will just be cleaver cout codes

    Then you got everything you need.. Read it in english

    You need 3 start odometer readings right?
    Code:
    float odostart1,odostart2,odostart3;// for the 3 start distances
    So now you need end distances?
    Code:
    float odoend1,odoend2,odoend3;// for the 3 end distances
    Then it's just a continuation of the same math problem,
    odostart-odoend = distance

    and miles/gallons = MPG


    The only problem I have is what are you Inputs?

    I didnt get any other information then what I stated....

    So I would start it kind of like this?....

    #include <iostream>
    using namespace std;

    float odostartone;
    float odoendone;
    float gallonsone;
    float odostarttwo;
    float odoendtwo;
    float gallonstwo;
    float odostartthree;
    float odoendthree;
    float gallonsthree;

    Yea, You need more tho...

    You can have comma's and run them rowed instead of collums

    float odostartone,odostarttwo,etc..
    but whatever works for you.

    You also need distance1,2,3(or miles1,2,3) and MPG1(2,3) etc

    cuz it's Miles/Gallons = MPG

    But without proper instructions your pretty much stumped.. you can set it up so you can enter odometer start and finish 3 times each.... as well ad miles drove and it will display everything.. but it's odd he just gave you a picture and vague instructions such as.. 3 lists of odometer start end, miles, gallons and mpg.. I gotta go to bed. So i hope someone else can help. If not I'll add more tomorrow

    So start with that, as in

    cout << "Enter start odometer";
    cin >> start;


    When you've input 3 values (as described), you have enough info to calculate the other two values.

    Can you do that much?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
