Write the following functions
Area of a Rectangle (Function)
The function should accept two arguments i.e. length and
width of the rectangle and should return the area of the
rectangle, the definition of the function is as under
int areaRect(int, int);
Use the function
Use the function areaRect() and develop a program that
allow user to enter the length and width of the rectangle,
the program will display the area of the rectangle calculated
by the function areaRect
Square or Not (Function)
Develop a function that accepts two integer values as length
and width of a shape and returns 0 or 1. A 1 will be returned
if the shape is a square otherwise a 0 will be returned, the
definition of the function is given below
int isSquare(int l, int )
Use the function
Write a program that will ask use to enter length and width
of a shape and will inform the user weather the shape is a
rectangle or a square.
Extension
Develop a program that will use the functions areaRect()
and isSquare(), the program will ask user to enter two
integer values as length and width of a shape, the program
will display type of shape i.e. square or rectangle and will
display the area of the shape as well.
How Many Squares (Function)
Ahmed has large number of wooden boards, he wants to cut
them into squares of different sizes to be used in decoration
of his house, develop a function that will accept the length
and width of the board along with one side of the square,
the function will return the number of smaller square boards
that can be made from the larger board.The definition of the
function is given below
int howManySuquares(int, int, int)
Driver Program
Develop a driver program to test the working of the function
developed for Ahmed
Extension (Function)
It is possible that the size of the board may be smaller then
the size of the square that have to be made from that
board, for such cases the howManySquares() function may
not perform well, extend the function and display an error
message, the function will return a negative value for such
cases, a negative value is a way to indicate that the function
cannot perform the desired operations
Extension (Program)
Extend the howManySquares() driver program and extend it
to demonstrate that the function performs well for wrong
inputs
Extension (Function)
Ahmed want to cut the board in smaller boards which may
or may not be squares, extend the howManySquares()
function and write a new function howManyRectangles(), the
function will accept four parameters as length,width of board
(larger), and length, width of required board piece(smaller),
the function will return the number of smaller boards of
desired dimension that can be made from the larger board
given. The definition of the function is given below
int howManyRectangles(int,int,int,int)
Driver Program
Write a driver program to demonstrate the working of
howManyRectangles() function,
Extension (Function)
Extend the howManyRectangles() function to cope the
problems such as the board provided to make smaller
boards is smaller then desired smaller boards
Driver Program
Write a driver program to demonstrate the working of the
extended howManyRectangles() function
