The purpose of the project is to manage the renting of boats.
For this project we distinguish types of boats according to the number of persons the boat can carry. Assume our company offers three types of boats: for 1, 2, and 3 persons. The task of the program is to help the client selecting a boat and to keep track of the number of available boats of each type.
Initially (i.e., only once at the start of the program), the user is asked to type in the number of boats of each type. Then the following menu is presented :
0. terminate the program;
1. see the number of available boats of each type;
2. rent a boat, of a type that is available;
3. return a boat.
If the user types in a number outside the range 0..3 when
selecting from the menu, the message
"Invalid option. Please Try again." should be displayed,
giving the user the opportunity to start over again.
You may expect that only integer numbers will be entered,
so you should not place guards for alphanumeric input.
When no boats of the requested type are available for renting, the user should receive a message, whereafter the main menu is shown again. The same type of message should be received when a boat of the wrong type is returned. When renting or returning available boats, the client receives an acknowledgement. For an example of such a confirmation, see the sample session below :

Mind spelling mistakes in the dialogue with the user and the output.
The first line of your program should be like
/* MCS 260 Project Three by <Author> */
where you replace the <Author> by your name.
The gcc compiler will be used to test your program. So even if you have developed your program in a Windows environment, test your code on icarus.cc.uic.edu with gcc. To ensure your program is written in ANSI C, compile with the option -ansi, e.g., like
gcc -ansi proj3.c
Programs that are not conform the ANSI C standard will
be discounted.
The printout of your program will be collected
at the start of the lecture on Friday 12 October, at 1PM.
Before the deadline, send the code by e-mail to
janv@uic.edu from your account on icarus.
If you saved your program in the file proj3.c,
then you send your program typing on icarus the following
command :
mail janv@uic.edu < proj3.c
This ensures your program is free from any encapsulations.
Note that the e-mail address is my university netid and not
the address at the MSCS department.
