Data type, variables and constants

Data type, variables and constants

1. Data type

   • Computers are complex, in order for programs to función correctly computers use basic Data and operations on that data. this data determines what type of values an object can have and what operations can be performed.
     • Numbers, booleans, characters, arrays, and structures. Some languages like ActionScript replace characters with "strings". Object oriented languages, such as C++ and Java replace "structures" with "objects"

2. Variables

   • A variable is something that may change in value. This makes data distinguish from one another. It si something to clarify or understand better. A the variable name must begin with a letter and may be followed by up to five characters (letters or numbers only).
     • For example the number of students that passed a math exam of

3. Constants

   • A constant is very simple, it is a value or an identifier that cannot be altered in a program. It has to maintain the same in order for the program to function correctly
     • For example n\ means ``new line´´
