Parameters in CSharp

      Parameters are defined so that the methods can be made more dynamic. Parameters of a methods can be of 2 types.

•  Input parameters.

• Output parameters.

       Input parameters are used for bringing values in the method for execution. Whereas output parameters are used for carrying a value ouut of the method after execution of the method

       By default every parameter we pass to a method is an input parameter and if we want to define a parameter as output parameter we need to prefix the parameter with ref or out keyword.

      public void test (int x,ref int y,out int z)

       Here x is an input parameter and y& z are output parameters.

Note: By using return types also we can send results out of a method, but only a single result whereas if we are sending results out of a method using output parameters we have a chance of sending more than 1 result at the time of execution.
