Document Summary

Reads a string that has been typed in using the keyboard. Expects one (optional) argument: the string to be displayed to prompt the user to type: function name (argument1, argument2) If used as the right-hand side of an assignment statement, the data typed is assigned to a variable. Since input can be used as a right-hand side of an assignment statement, it is said to have a (cid:862)return value(cid:863) Input produces return value: ex. when this function has completed, there is a value given to the program that o(cid:396)igi(cid:374)all(cid:455) (cid:862)called(cid:863) it. The (cid:862)input(cid:863) function once called, will return a string. The (cid:862)print(cid:863) fu(cid:374)(cid:272)tio(cid:374) e(cid:454)pe(cid:272)ts a(cid:374) argument; this argument can also be a string. These function calls can be chained together to create an (cid:862)echo(cid:863) utility.
