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
Functions have independent existence means they can be defined outside of the class. Ex:- main() function in C, C++ Language
Functions are defined in structured languages like Pascal, C and object-based language like javaScript
Functions are called independently.
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
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
Methods are defined in object-oriented languages like C#, Java
Methods are called using instance or object.
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);
}
}
