prototype

And if Jordan were but Jaar Eden, that is, the Riuer of Eden, Geneſar but Ganſar or the Prince of Gardens; and it could be made out, that the Plain of Jordan were watered not comparatively, but cauſally, and becauſe it was the Paradiſe of God, as the Learned Abramas hinteth, he was not far from the Prototype and originall of Plantations.

The prototype had loose wires and rough edges, but it worked.

Like any variable in a C program it is necessary to prototype or declare a function before its use, if it returns a value other than an int. It informs the compiler that the function would be referenced at a later stage in the program. / For example, / In program 1, the statement / void display_message(); / is a function prototype or declaration. Here void specifies that this function does not return any value, and the empty parenthesis indicate that it takes no parameters (arguments).

A robin is a prototype of a bird; a penguin is not.
