Whats wrong with my find Circle Area program?[compiles fine]

I know there are some easier ways to perform this but I'm trying to get used to pointers and arrays[samething]. When the user types in the radius it doesn't return the current area.(pie * r2)

Code:

#include <iostream>

inline float GetArea(float *buffer, float radius)
{
 buffer= new float[5];
 buffer[2]= radius * radius;
 buffer[1]= 3.14;
 buffer[0]= buffer[2]*buffer[1];
 return buffer[0];
}

int main(int argc, char **argv)
{
 float mybuffer, radius;
 cout << "Input the radius: ";
  cin >> radius;
 GetArea(&mybuffer, radius);
 cout << "The Area is: " << &mybuffer;

 cin.get();
 return 0;
}

what do you want the program to do becuz if u just want it to find the area than i think it can be done much more easily

GB knows this but GB is tryin to use pointers...

and arrays..

Looks like someone didn't really read my post

ok. then i dont see the problem with his code maybe you can help.

( i was the unregistered person)

ok

if you can get the code post it i want to know whats wrong with it
let me know it that help plz



#include <iostream.h>
#include <conio.h>
double mult(double x, double y);

int main()
{
double x, y = 3.14;
cout<<"Please input your radius: ";
cin>>x;
cout<<"The area is "<<mult(x, y);
getch();
return 0;
}
double mult(double x, double y)
{
return x*y*x;
}


this is a way of doing it w/ a function it works. i used getch() for my stupid compiler closing when i launch the program

uh dude... use code tags... or youll be hated here....

put [ code ] and [ / code ] around your code.

without spaces of course..

i dont quite catch what your saying im kind of new here hehehe do you mean


code:


#include <iostream.h>
#include <conio.h>
double mult(double x, double y);

int main()
{
double x, y = 3.14;
cout<<"Please input your radius: ";
cin>>x;
cout<<"The area is "<<mult(x, y);
getch();
return 0;
}
double mult(double x, double y)
{
return x*y*x;
}





like that

no like
this

Code:

	
Code:
	
 < put that above your code
 

<<that below your code...

Ok, over here we use a web development language known as PHP. Very similiar to HTML. If you want your source code to be readible you must go like this [ code ] before your code, and to end it you go like this [ /code ]. I know how to do this the simple way.

Code:

#include <iostream>
#define done 0

inline float Area(float pie, float radius)
{
 return pie*(radius*radius);
}  

int main()
{
 float x;
 cout << "Input the radius: ";
 cin >> x;
 cout << "The Area is: " << Area(3.14, x);

 cin.get();
 return done;
}

But I won't to do it the pointer/array way.

thanks and did you figure out you code problems yet i really want to know whats wrong cuz i cant figure it out

that code does work so i guess its figured out the easy way then

After the user types in the radius, it doesn't return the proper area.

maybe you have the wrong formula or maybe you checkec it wrong cuz it workes for me, both of the codes mine and the other one. area = pie * radius^2
