5.3 There are some important conditions for using the VAR keyword:

Can only be used for local variables, not for fields;

Can only be used when initialization is included in a variable declaration;

Once the compiler infers the type of the variable, it is fixed and cannot be changed.

The important thing to remember about parameter arrays is that when arrays are created in the heap, the values of the arguments are copied into the array. In this respect, they are like value parameters.

If the array parameter is a value type, then the value is copied, and the argument is not affected by the inside of the method.

If the array parameter is a reference type, then the reference is copied and the object referenced by the argument can be affected by the inside of the method.
