problems in functions

[Bollom]

guys i really have big problem

i need some one make this program work correctly

because our doctor want it today


#include <iostream>

#include <cmath>

using namespace std;

double finddistance (int x1,int x2,int y1,int y2)

{
double distance;

distance= pow((x2-x1),2) + pow((y2-y1),2);

distance= sqrt(distance);

return (distance);
}



double findr (int x1,int x2,int y1,int y2)

{
double r;

r= pow((x2-x1),2) + pow((y2-y1),2);

r= sqrt(r);

return (r);

}


double findcf (double r)

{
double cf;

cf=2*r*3.1416;

return (cf);

}


double findarea (double r)

{
double area;

area= pow(r,2) * 3.1416;

return (area);

}


int main()

{
int x1,x2,y1,y2;
double r;

cout<<"Enter the center point (X1,Y1)"<<endl;
cin>>x1>>y1;


cout<<"Enter any point on the circle (X2,Y2)"<<endl;
cin>>x2>>y2;

cout<<"The Distance ="<<" "<<finddistance (x1,x2,y1,y2)<<endl;

cout<<"The Radius ="<<" "<<findr (x1,x2,y1,y2)<<endl;

cout<<"The Diameter ="<<" "<<findr (x1,x2,y1,y2) * 2<<endl;

cout<<"The Circumference ="<<" "<<findcf (r)<<endl;

cout<<"The Area ="<<" "<<findarea (r)<<endl;



return 0;

}





and thanks in advance

You should say the errors you get ( http://www.cplusplus.com/forum/articles/1295/ )
and use [code][/code] tags

to solve ambiguity for pow: pow((x2-x1),2.0) cout<<"The Radius ="<<" "<<findr (x1,x2,y1,y2)<<endl; does not set the variable r (after called in findcf and findarea) to have the value of the radius
