In programming langauages we have two concepts functions and methods. functions are defined in structural language and methods are defined in object oriented langauge. The difference between both is given below :

Functions

  1. Functions have independent existence means they can be defined outside of the class. Ex:- main() function in C, C++ Language

  2. Functions are defined in structured languages like Pascal, C and object-based language like javaScript

  3. Functions are called independently.

  4. Functions are a self-describing unit of code.

 //function main in C
void main()
{
 int a,b,c;
 a=5;
 b=6;
 c=a+b;
 printf("Sum is : %d",c);
} 

Methods

  1. Methods do not have independent existence they are always defined within a class. Ex:- main() method in C# Language that is defined within a class

  2. Methods are defined in object-oriented languages like C#, Java

  3. Methods are called using instance or object.

  4. Methods are used to a manipulate the instance variable of a class.

 //method sum in C#
class demo
{
int a,b,c;
public void sum()
{
 a=5;
 b=6;
 c=a+b;
 Console.WriteLine("Sum is : {0}",c);
 }
}
