C is the mother programming language of C++. It is a procedural programming language which means that everything is executed in a certain order. This order can be changed through the use of control loops.

[edit] Syntax

C=C+1
C+=1
C++

All of these increment 1 to the variable "C". The three statements are equivalent, although when compiled the last statement will be slightly more efficient than the previous two. "C+=1" is also more efficient than "C=C+1". 

C=C-1
C-=1
C--

All of these subtract 1 from the variable "C".

[edit] Data Types

C requires a data type for each piece of data that is defined by the programmer. The predefined data types in C are:

  • void: no specific data type
  • int: integer number, usually takes up 4 bytes
  • char: single character as defined in the ASCII table, uses 1 byte
  • float: floating point number with a certain precision, usually takes up 4 bytes
  • double: floating point number with a greater precision than a float, usually takes up 8 bytes
