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.
In foods, shellac is most commonly used as a coating or glaze on confections, chewing gum, fruit, and coffee beans. Lac dye, red like carmine, (another insect product), may be used as a coloring in foods and beverages.: Shellac is a coating or glaze derived from the hardened, resinous material secreted by the lac insect, much like honey from a bee. Shellac in its raw form, known as âlac resin,â along with lac wax and lac dye, is produced in Southeast Asia.
