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 is an animal product, a resin secreted from the Coccus lacca (lac beetle), a scale that feeds on certain trees in India and southern Asia. After hatching, the nifty little bug snoops around for a place to eat, selecting a stem or leaf as its breakfast counter.any vitamins, pills and food supplements are coated with shellac to make them slide easily down your throat, into your tummy. Of course the most important use of shellac, in my not-so-humble opinion is as a woodworking finish, where you can make your projects shiny and eye-catching.
