Having the prototype available before the first use of the function allows the compiler to check that the correct number and type of arguments are used in the function call and that the returned value, if any, is being used reasonably. The function definition itself can act as an implicit function declaration.
While shellac is not usually the finish paint choice, it is often thought of as the best paint primer available. It has properties that oil and water based paints can't match, and provides a more dependable seal than most other primers are able to provide.
A shellac finish has been used by woodworkers since the early 1800's. It has many advantages: shellac is non-toxic, can be used as a sealer before applying a stain (to even out the stain's application), can be mixed with nearly any color, and is very easy to repair in the event of damage from use.hen pad or brush on a series of coats of shellac and rub it out until the finish is even. Should a surface scratch appear through the finish, use a fine artist's brush to fill the scratch with shellac. Rub out the finish to even out the color between the repaired scratch and the surrounding finish.
