There is no algorithm there, just a simple logic. The logic is what you have done in your code. It should know yourself.

Code:

Check the number of command line parameters.

   If 2 command line parameters not found, notify it to the user,

   Else display command line parameters.

      Convert parameters to integer values and add one to each.

      Set the array size equal to calculated values.

      If any parameter is zero, display the value zero.

      Else, for each array element add values of multiplication of each index.

Exit.

This is the very simple logic in the code.
