Problem Statement:
Write the C++ language program
to calculate the slope of the line that is passing through two points and
displays one of the following five messages according to the nature of the
slope.
Detailed Description:
Your program will ask for the two
inputs for the starting point P1(x1,y1) of the line i.e. XCoordinate and
YCoordinate, and two inputs
for the ending point P2(x2,y2) of the line i.e. XCoordinate and YCoordinate.
Formula to calculate the slope
of the line is
Slope = difference between y
coordinates/difference between x coordinates
Slope can be one of the following
five types depending upon its value.
Line will make the 45 degree
angle with the horizon
Line will travel more along XAxis and Less along YAxis
Line will travel more along YAxis and Less along XAxis
Line is parallel
to YAxis.
Line is parallel
to XAxis.
For example Consider a line which passes through two points
p1(10, 10) and p2(20, 18).
Your program should ask for
Xcoordinate of the starting point i.e. 10
Then it should prompt for the
Ycoordinate of the starting point i.e.
10
Similarly your program will ask
for the X and Ycoordinates of the ending point of the line i.e. 20 and 18
respectively.
Now difference between y coordinates
is dy = = 18 – 10 = 8
Whereas difference between x
coordinates is dx = = 20 – 10 = 10
Then message should be
displayed according to the nature of the slope of the line. In this case following message will be
displayed.
Line
shall travel more along Xaxis and Less along Yaxis.
Sample run of
the program:
