What is the difference between a parameter and variable?

Dhanush K

I'm confused between these two terms "Parameters" and "Variables". What is the difference between a parameter and a variable? Give one example for each of them.

In c# context
Paramaters are passed into the function and Variables are declared inside functions to hold temp values to be used further down in the function.

Parameters

Public void MyFunction(string param1, int param2, double param 3)
{
.........
}

Varibales
Public void MyFunctionWithoutParam()
{

string variable1 = "C# Corner";
string variable2 = "is awesome";
string varibale3 = varibale1 + variable2;

console.writeline(varibale3);

}

Variables can be created inside functions (locally) and outside functions. Variables can be created as members of a class and when they are a member of the same class as a method then the method can access the variable, usually without restriction. Varaibles can be passed as an argument. Variables can be instances of a class and when an instance of a class is passed as an argument to a method then all public members of the class is accessible to the method.
