Question 1 - 15 marks
Write a C program that prints out all di\x0berent possibilities of obtaining $2(2
pounds) using coins of values 2 pence,5 pence,and 10 pence.Indicate how
many possibilities have been found.The output of your program may look like:
$2 = 100 x 2p
$2 = 90 x 2p + 4 x 5p
$2 = 80 x 2p + 8 x 5p .
In total,there are possibilities to make $2.
Note that (no.of the possibilities) is calculated by your C program.
Question 2 - 15 marks
Write a C program that reads m x n matrix "A" and p x q matrix "B",checks
whether these matrices are multipliable in either order or not (e.g.whether A
x B or B x A is de\x0cned).Further,if A x B or B x A is de\x0cned then calculates
the product and prints out the result.
Question 3 - 20 marks
Write a C program that initializes an array of integer and then copies the con-
tents of the array into two other arrays.Declare all arrays in the main program.
To make the \x0crst copy,write a function,which uses the array notation (the
square brackets []) to access the elements of the array.
To make the second copy,write a function that uses the pointer notation and
pointer incrementing to access the elements of the arrays.
Each function takes the name of the source array,the name of the target/destination
1
array and the number of elements to be copied as function arguments.
Here is an example showing how the functions should be called giving the fol-
lowing declarations:
int source[4] = {1,2,4,6};
int destination1[4];
int destination2[4];
copy_array(source,destination1,4);
copy_ptr(source,destination2,4);
Question 4 - 50 marks
A ferry has a seating capacity of 30 arranged as 10 rows (1 to 10) of three seats:
A,B and C (i.e.the seat identi\x0ccation labels are 1A,1B,1C,...).It makes one
trip a day.Write a seating reservation program in C with the following features:
1.The program uses an array of 30 structures.Each structure should hold a
seat identi\x0ccation label,a
ag that indicates whether the seat is assigned,
the last name of the seat holder (max 30 characters),the \x0crst name of
the seat holder (max 30 characters),and the price of the seat (the price
arrangement is up to your choice).
2.The program displays the following menu:
To choose a function,enter its letter label -
\x0f (a) Show assigned seats with passenger names.
\x0f (b) Show list of the cheapest seats available.
\x0f (c) Show list of the most expensive seats booked.
\x0f (d) Assign a customer to a seat.
\x0f (e) Edit customer details,for a speci\x0cc seat.
\x0f (f) Delete a seat assignment.
\x0f (g) Quit.
After executing a particular function the program should show the menu again
except for choice (g).
Hints:The program might save the data in a \x0cle between runs and load the
data (if any) at the start of the program.
