One way you can test code is to do informal testing as you write the program. After writing a unit of code (a function, a class, or some other discrete “package” of code), you can write some code to test the unit that was just added, and then erase the test once the test passes.

How parameters and arguments work together. When a function is called, all of the parameters of the function are created as variables, and the value of each of the arguments is copied into the matching parameter (using copy initialization).
