Question

Please use my Lab 3.2 code for this assignment

Lab 4.2 instruction

Using the code from lab 4.1, add the ability to read from a file.

Modify the input function:

      * Move the input function out of the Cargo class to just below the end of the Cargo class

      * At the bottom of the input function, declare a Cargo object named

        temp using the constructor that takes the six parameters.

      * Use the Cargo output function to print the Cargo object.

      * Call the input function from the main function with no arguments. Remove the rest of the code

         from main

3. Create a file and use it for input. This is good because you will be

      using the input many times.

* Create a file named cardata4.txt (or use the one provided),

containing the following three lines of data.

If you create your own, make sure to follow the format

below:

Pallet          PAG    PAG45982IB   737   4978   OAK

Container AYF     AYF23409AA 737    2209   LAS

Container AAA    AAA89023DL 737   5932   DFW

      * All weights are in pounds, don’t worry about kilograms. You may

         comment out that code.

      * In the input function, declare an object of type ifstream named

        inputFile, which we will use to read from the file.

      * At the beginning of the code for the input function, open the

        file. If the open fails, send a message to stderr and exit the

        program.

      * In all the reads within the input function, remove the user

        prompt and read from the inputFile object, rather than reading

        from the stdin object.

      * Hint: We need to use getline when reading the strings.

        using >> skips leading white space before reading the data.

        getline does not skip this leading whitespace. So, before using

        getline use the following code:

                while(inputFile.peek() == ' ')

                     inputFile.get();

        peek looks at the next character you are about to read. If it is

        a space, get is used to read the space character, to get it out

        of the way. Your output will then be much neater.

      * Use a loop to read each line from the file. To do this use a

        while loop including all the reading in the input function, as

        well building and output of the Car.

        Hint: you can do this with the following while statement:

                while(inputFile.peek() != EOF) or use this form while(inputFile >> type)

               

        The peek function will return EOF if there is no next character.

      * At the bottom of the input function, close the file.

Put an eye catcher before the beginning of each function, class, and the

global area:

// class name function name comment(if any)
