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

[Golden Bunny]

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)

#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

[gamer4life687]

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

( i was the unregistered person)

[Golden Bunny]

ok

[gamer4life687]

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

[Vicious]

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

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

without spaces of course..

[gamer4life687]

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

[Vicious]

no like
this

	
	
 < 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.

#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.

[gamer4life687]

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

[gamer4life687]

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

[Golden Bunny]

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

[gamer4life687]

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
