C++ Program

A   sequence   of    structured   statements   written   by programmer using C++ language to solve a problem.

Using Visual C++ to write your program

1- Start à Programs à Microsoft Visual Studio 6 à Microsoft Visual C++ 6

2- File à New à Files à C++ Source file à oK

3- Write your program using C++ statements

4- Compilation: Ctrl + F7 to see if the program has error's

5- Execution: to display the program’s result

Remarks:

- iostream.h: C++ library that contains all input/output statements and other constrols.
- main(): the main function of the program which represents the program’s life time.
- a, b, and s are three variables of type integer. Their values can be any integer and can be changed.
- cin>>: C++ statement to take value(s) from the user.
- cout<<: C++ statements to display value(s) to the output screen.
- " ": must be around any character constants.
- \n or endl: to start new line at output screen.

Variables

Variables:

  - Variable is one memory location.

    -The name of the location is the variable name.

    -The location content is the value of the variable

   - You can change the content of the variable at any

      time in the statements of the algorithm.

e.g.

    Name of the location        Inside Memory location

     employee_name      "Ali Ahmed"

     age        35

     hourly_rate        3.25

Data Types :

Predefined Data Types:

•int : values (e.g.   5  ,  -321 , 12)

          operations (e.g. + , - , * ,  / ,  % , >, <, = =, !=, > =, <= )

•float (double) : values  (e.g.  3.2 , 1.23E+5 , 0.34E-2)

                  operations (e.g. +, -, *, /, , >, <, = =, !=, > =, <= )

•bool : values  (true  ,  false)

                 operations (e.g.   AND, OR, NOT)

•char : values (e.g.  ‘A’ , ‘t’ , ‘(‘  , ‘5’ , ‘;’    )

                 operations (e.g. <, > , ≤, etc.)..........
