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.
For example: water resistance watches can be worn under rain, not in the pool or for going scuba diving. Water resistant bags will be able to take rain slight water spill, but the owner wonât be able to dunk the bag in a bucket of water. This is the major difference between water resistant and water proof. Water proof states that in no condition will the product become wet or damaged if submerged under water, while water resistant states that the product will not be damaged if it is exposed to water or liquid under certain conditions.
