DOS and BIOS

Write a stopwatch program that will display time in letters approximately 2 inches high and 1 inch wide. Display minutes, seconds, and tenths of seconds. Have the elapsed time reset to 0.00.00 when the r key is pressed, and then begin time when the t key is pressed. Stop timing, and freeze the display, when the t key is pressed the second time.

Basic Elements of C++

1. Discuss the importance of defining the problem and what can happen if the problem is not defined properly. Note that in class problems will be defined, however in the business world a great deal of time would need to be devoted to properly defining the problem (in terms of input and output) so everyone has a clear understanding of what needs to happen. 2. Why are there different versions of the same programming language?

Building Classes

Write a program to do rational number arithmatic, representing each rational number as a class that has instance variables for the numerator and the denomonator. The program should read and display all rational numbers in the format a/b, or simply a if the denominator is 1.

Classes and Enumerators

Use the type Date (consisting of a month name, day number, and a year number) to develop a class Event to model events scheduled for specified dates. use this class in a program that reads several events and stores these in a vector of Events. After all the events have been entered, the program should display a schedule of events in chronological order.

Classes and Enumerators

Write a program similar to the following: wavelength.cpp computes the wavelength of light for a fiven Color. Input: theColor, a Color value Precondition: theColor is one of RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, VIOLET Output: the wavelegth of light corresponding to theColor, but that uses the Color class hierarchy.
