Local Variables

In the factorial example there were actually two functions -- main and Factorial. Each function declares some variables:

In general, when inside a function, you can only refer to the variables declared within it, its local variables. The formal parameters of a function are also local variables that may be used within that function.

What happens if we have two variables with the same name? -- You will always be using the local one.
