Parameters vs. Arguments

Do I have this straight:

Parameters are a list within a function header of accepted data types.
Arguments are the actual values that are passed to the function with respect to the parameters.

Right?

Absolutely correct.

parameters are used while defining or declaring a function e.g. int a,int b in the declaration
void dummy(int a,int b);

arguments are the actual values passed to the function when a function is called e.g. 2,3 in
dummy(2.3);

Ahhh, thank you, Karam!
