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.
Traditional Shellac. Shellac is a penetrating varnish that's been used on American table tops since Colonial days. A shellac finish allows you to view the wood detail with remarkable clarity. Amber shellac provides the same clarity but it also adds warmth to light-colored woods such as pine or oak. properly protected wood table will last for generations, yet the table top is particularly vulnerable to scratching, scraping and moisture. Sealing that surface requires a tough, transparent water-resistant coating that highlights the beauty of the wood beneath.
