Difference between an argument and a parameter.

A parameter is a variable that is declared in a method and receives a value when the method is called.

An argument, on the other hand, is the actual value that is passed to a method when it is called.

Check the snippet given below to know the difference:

In this example, the add() method takes two integer parameters, num1 and num2. When the add() method is called with the arguments a and b, the values of a and b are passed to the num1 and num2 parameters respectively.

Inside the add() method, the values of num1 and num2 are added together and the result is returned.
