You do not have to use prototypes; so long as you define the function before you use it, it will work. In addition to Bazzy's words, if you ever want to use a function that you did not write and are not going to be compiling yourself (which I expect is very, very often), the compiler must still know what will be passed in and what will be returned.

Many myths cloud the emergence and prominence of shellac after the appearance of nitro cellulose. One chief legend states shellac is not waterproof. Shellac, just as many other finishes, is not waterproof, however, it is quite water resistant. Shellac can easily withstand water for about 4 hours. Even if the surface is not wiped, the resulting faint white stain will still fade away as it dries.
Shellac finishes should be kept away from water, as they will become dull or even have a white residue appear when exposed to moisture. Should your shellac finish develop water spots, repair is relatively simple. Use straight alcohol on a pad and remove the shellac from the offending area.Then 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.hen pad or brush on a series of coats of shellac and rub it out until the finish is even.
