Dear Class:

Grades are done... hallelujah! Please check. I need some work from some of you from the database.

The first programs are simple but you need to practice these programs to get them to work properly. Make sure you understand the five parts of the basic structure of a C++ program: 1) Compiler directive #include, 2) Main Function, 3) Braces to mark the beginning and end 4) Statement followed by a ; last statement is return 0; and 5) can also have comments which are ignored by the compiler but necessary to the programmer.

We need to break down your programs.

We will be talking about the five basic data types: int, Float, Double, char, and void. Assignment statements. These will be important in the developing an algorithm and coding the problem. This will take us into the first half of Chapter 2. We will look at this together!

Chapter 2
Binary Code

Good day to you! We will begin with looking and naming variables. To initialize a variable you simply assign it a value. You must declare a variable before you can use it. On page 29-30, there are examples of keywords and improper C++ variable identifiers. Check out the character and equivalent decimal value located on page 30.

Do 2-1 in book on page 27 and then do the step by step 2-2. Do step 2-3 on page 29 and check if there is a difference? We need to look at Floating Point Variables, Boolean Variables, and Constants. Do code list 2-3 on Page 34. Do code list 2-4 on page 36.

Finally, please enter, compile, and run Project 2-2 on page 40. This will probably bring us to the end of the class.

Sincerely,
Mr. Green-Hite
