PROGRAMMING

1. Varibles

   • A data item that may take on more than one value during the runtime of a program.

2. Data Types

   • Boolean
     • The Boolean data type is a data type, having two values, intended to represent the truth values of logic and Boolean algebra.
   • Char
     • A character is a display unit of information equivalent to one alphabetic letter or symbol. This relies on the general definition of a character as a single unit of written speech.
   • String
     • A string is traditionally a sequence of characters, either as a literal constant or as some kind of variable.
   • Integer
     • An integer is a number that can be written without a fractional component.
   • Real
     • A real number is any positive or negative number. This includes all integers and all rational and irrational numbers.

3. Selection

   • In a selection structure, a question is asked, and depending on the answer, the program takes one of two courses of action, after which the program moves on to the next event.

4. Iteration

   • Iteration is used in computer programs to repeat a set of instructions.
   • Condition

5. Arrays

   • An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created.
