Tamilnadu Samacheer Kalvi 12th Computer Science Notes Chapter 1 Function Notes

Expression of Algorithm:
Algorithms are expressed using statements of a programming language

Subroutine:
Subroutines are small sections of code that are used to perform a particular task that can be used repeatedly.

Function:

  • A function is a unit of code that is often defined within a greater code structure.
  • A function contains a set of code that works on many kinds of inputs and produces a concrete output.

Definition:
Definitions are distinct syntactic blocks.

Parameters:
Parameters are the variables in a function definition.

Argument:
Arguments are the values which are passed

  • An interface is a set of action that an object can do.
  • Interface just defines what an object can do, but won’t actually do it.

Implementation:
Implementation carries out the instructions defined in the interface.

Pure functions:
Pure functions are functions which will give exact result when the same arguments are passed.

Impure function:
The functions which cause side effects to the arguments passed are called Impure function.

Recursive function:
A function definition which calls itself is called recursive function.
