SC$10032023/24$ Sem $2$ Assignment

The NTU Express Train consists of one train with a seating capacity of $5.$ It makes one trip

monthly. You are required to write a seating reservation program. You may use an array of $5$

structures for building the program. Each structure should hold: $(1)$ a seat number that has a

value between $1$ and $5$; $(2)$ a marker $($status$)$ that indicates whether the seat is assigned $($e$.$g$.,$

EMPTY or OCCUPIED$)$; and $(3)$ the customer name of the seat holder. The seat number must

be unique. Therefore, each structure will have a different seat number when it is created.

You may assume that the name of a customer is not more than $40$ characters long.

The program should display a menu to support the following functions:

$(1)$ listOccupiedSeat$()$ The function requirements are given below:

$$ The function prints the list of seat assignments.

$$ It prints the following message when it is executed: "listOccupiedSeat$()$:$".$

$$ If all seats are empty, the function should display the message: "The seat

assignment list is empty".

$(2)$ assignSeat$()$ The function requirements are given below:

$$ The function assigns a customer to a seat. It reads in the selected seat number and

customer name from user, and then assigns the seat accordingly.

$$ It prints the following message when it is executed: "assignSeat$()$:$".$

$$ After assignment, the message $$The seat has been assigned successfully$$ should be

displayed.

$$ The program should issue a message $$Occupied$!$ Please choose another seat$,$ if the

selected seat has been assigned to another customer already.

$$ The program should issue the message $$The train is full$$ if the train is full $($i$.$e$.5)$

during seat assignment.

$$ The program should issue the message $$Please enter a seat number between $1$ and

$5$ if the selected seat number is not between $1$ and $5.$

$(3)$ removeSeat$()$ The function requirements are given below:

$$ The function removes a seat assignment. It reads in the selected seat number from

user and then remove the assigned seat accordingly.

$$ It prints the following message when it is executed: "removeSeat$()$:$"$

$$ After seat removal, the message $$Removal is successful$$ should be displayed.

$$ During seat removal, the program should issue the message $$All the seats are

vacant$$ if all the seats are empty.

$$ If the selected seat is empty, the function should issue the message $$Empty$!$ Enter

another seat number for removal$.$

$$ The program should issue the message $$Please enter a seat number between $1$ and

$5$ if the selected seat number is not between $1$ and $5.$

You are required to write the program and the functions according to the program

requirements. Note that:

$$ You should design the program and define the functions according to the

requirements $($please refer to the sample test cases for program implementation$).$

Page $2$

$$ You only need to consider the requirements stated in the program specification, and

you do not need to implement any user input checking which is not stated in the

specification.

$$ You may add any other supporting functions in the program if needed.

$$ You may include any C library functions in your program if needed.

$$ Sample test case are given below.

A sample program running session is given below $($please note that the input data are shown

in orange color$)$:
