hi i appreciate your assisstance.

how would you approach these two questions.

1) The distance between 2 points in a co-ordinate system is given by the formula
√(x1-X2)²+ (y1-y2)²
Write a program to read in the coordinates of two points and write out the distance between them.

2) Statistics of the rainfall for a town has been collected for ten years. Write a program to read the in the information for ten years and present the results in form of a histogram. Assume the rainfall ranges from 0-200 mm. (output as a horizontal histogram)



the codes would be appreciated
 

Re: c++ programming

Hi nyadimo,

This is very basic and simple and it looks like a homework signment.
I'd like to help you, but I shouldn't do your homework for you. ;-)
So I will give some hints, instead of the complete sourcecode to do it...

1.
x^y can be calculated with the function pow(x,y) (be sure to include <math.h>)

2.
This is very dependant on the libraries to your disposal.
If you use VC it's dependant on weather your program is a MFC appl with a doc/view structure, or a dialog or even a console...
You can only expect to get help on this subject if you specify this more precisely.

Hope this helps,
JB
 

c++ programming

For Root use sqrt(), and for square use Pow() method of math.h use simple formula for calculating distance
