The lab midterm will cover Chapters 1-5 and 12 in the Savitch text.  See the Midterm review document for the programming related material you should be familiar with from Chapters 1 - 2. 

Chapters 3 & 4 - Functions

You will be asked to write a function to do some task.  You will have to provide the function's declaration, header, definition (header + body), and call.

Know the difference between parameters and arguments and their relationship.  Know what it means to call-by-value and to call-by-reference using reference parameters.  Know how to use the return statement to pass a value back to the calling program.

You should be able to define (and use, if appropriate) the following terms: global variable, local variable, scope.

Chapter 12 (12.1 and 12.2) - File I/O

I/O file streams and data files. Be able to use ifstream and ofstream objects to read and write data to a file. Know the open(), close(), fail() and eof() functions. Also, know the different ways to determine the number of records in a data file: 1) including this number as the first entry in the file, 2) using a sentinel as the last entry, and 3) checking for the end-of-file mark.

       const int ITEMS = 4;
    double temperature[ITEMS] = {99.1, 98.3, 94.6, 95.5};

Know how to use array subscripts (e.g., temperature[i]), especially in a loop.

Know how to pass an array to a function.  Remember, use the array name in the function call, along with the size of the array:

        max = maxi( temperature, ITEMS); // call

Also remember that the function must know if a parameter is an array - use [] to indicate it:

       double maxi(double temp [], int SIZE)  // header

Know how to declare and initialize two dimensional arrays.

Know how to pass 2D arrays to functions.  Remember that the number of column elements must be provided:

    void display( double temp[][limit], int nrows, int ncols)
