A compiler is a computer program that accepts programs written in high level language and produces an object program.

If… Else… EndIf statement

If [Statement] then                              &n

Delete the record

Delete record [Record no.], Delete for [Statement] E.g.

 Brettell uses E.O.F. function in common, so this section will only mention about EOF() function. This function usually uses with Do-While statement. E.g.Set default to “P:\FoxPro”    

A class is the code for an object and an object is the instance of a class in memory. When you create an object from a class it is called instantiating the object.

A definition by its official site:-

"A class is a blueprint or prototype from which objects are created. This section defines a class that models the state and behavior of a real-world object. It intentionally focuses on the basics, showing how even a simple class can cleanly model state and behavior."

Object oriented programming or OOP is a way of writing programs using objects where each object has its attributes and set of operations defined by its class. An object is a data structure in memory that has attributes and methods. The attributes of an object are the same as variables and the methods of an object are the same as functions or procedures.

In the programming language C, an identifier is a combination of alphanumeric characters, the first being a letter of the
alphabet or an underline, and the remaining being any letter of the alphabet, any numeric digit,or the underline. Two rules must be kept in mind when naming identifiers.

• The case of alphabetic characters is significant.
• As C is defined, up to eight significant characters can be used and will be considered significant. If more than eight are used, they may be ignored by the compiler

The definition of a variable will assign storage for the variable and define the type of data that will be held in the location.

• Int
• Float
• Char
• Double

The three data types above have the following modifiers.

    * short
    * long
    * signed
    * unsigned

An array is a mean to store collection of values in a single variable. e.g instead of creating a separate variable to store each employee's name, you can use an array to store the names of all your employees in a single variable. This is how you would do it.

$employee_names[0] = "value1";
$employee_names[1] = 10;      //No matter of data type Wow..!
$employee_names[2] = "Susan";

A technique for organizing and coding computer programs in which a hierarchy of modules is used, each having a single entry and a single exit point, and in which control is passed downward through the structure without unconditional branches to higher levels of the structure. Three types of control flow are used: sequential, test, and iteration.

A structured program is one consisting entirely of three types of logic structures:
