: 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.
| Message No | Description |
1
|
Line will make the 45 degree angle with the horizon |
2
|
Line will travel more along X-Axis and Less along Y-Axis |
3
|
Line will travel more along Y-Axis and Less along X-Axis |
4
|
Line is parallel to Y-Axis. |
5
|
Line is parallel to X-Axis. |
Detailed Description:
Your program will ask for the two inputs for the starting point P1(x1,y1) of the line i.e. X-Coordinate and
Y-Coordinate, and two inputs for the ending point P2(x2,y2) of the line i.e. X-Coordinate and Y-Coordinate.
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.
- Slope=1
- Slope<1 li="">
- Slope>1
- Your program should have a check for the value of difference between X coordinates of the two points i.e. dx. In case difference between x coordinates is zero then slope should not be calculated in your program and following message should be displayed.
Line is parallel to Y-Axis.
- Your program should have a check for the value of difference between Y coordinates of the two points i.e. dy. In case if the difference between y coordinates is zero then following message should be displayed.
Line is parallel to X-Axis.
For example Consider a line which passes through two points p1(10, 10) and p2(20, 18).
Your program should ask for X-coordinate of the starting point i.e. 10
Then it should prompt for the Y-coordinate of the starting point i.e. 10
Similarly your program will ask for the X and Y-coordinates 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 X-axis and Less along Y-axis.
