c++ help

[Tinny]

hey guys, i tried to write a program that would convert cartesian coordinates to spherical. but my compiler is giving me an error, what did i do wrong? here's the code:

 

#include <iostream.h>

#include <stdlib.h>

#include <math.h>

int main()

{

float x, y , z, rsq, yox, rho, theta, thetad, zor, phi, phid;

cout << "Input the cartesian coordinates." << endl;

cout << "x:";

cin >> x;

cout << "\n";

cout << "y;";

cin >> y;

cout << "\n";

cout << "z;";

cin >> z;

rsq = x*x + y*y + z*z;

yox = y / x;

rho = sqrt (rsq);

theta = atan (yox);

thetad = theta * 180 / 3.1415926535898;

zor = z / rho;

phi = acos (zor);

phid = phi * 180 / 3.1415926535898;

cout << "The spherical coordinates are (" rho "," theta ", and" phi")";

cout << "\nWhere Rho is:\t" rho;

cout << "\nTheta is:\t" theta "radians or" thetad "degrees";

cout << "\n and Phi:\t" phi "radians or" phid "degrees.";

system("PAUSE");

return 0;

}

[matt--]

Changes are un-bolded.

system("PAUSE");

return 0;

}

 

That should do it.

Damn you... beat me to it

i'm sure its not all that hard to do once you sit your butt down and study it. It just takes time, will, and patience.

I though the same thing... but here are the differences, if anyone is sill interested

#include <iostream.h>
#include <stdlib.h>
#include <math.h>
int main()
{
float x, y , z, rsq, yox, rho, theta, thetad, zor, phi, phid;
cout << "Input the cartesian coordinates." << endl;
cout << "x:";
cin >> x;
cout << "\n";
cout << "y;";
cin >> y;
cout << "\n";
cout << "z;";
cin >> z;
rsq = x*x + y*y + z*z;
yox = y / x;
rho = sqrt (rsq);
theta = atan (yox);
thetad = theta * 180 / 3.1415926535898;
zor = z / rho;
phi = acos (zor);
phid = phi * 180 / 3.1415926535898;
cout << "The spherical coordinates are (" [color=red]<<[/color] rho [color=red]<<[/color] "," [color=red]<<[/color] theta [color=red]<<[/color] ", and" [color=red]<<[/color] phi [color=red]<<[/color] ")";
cout << "\nWhere Rho is:\t" [color=red]<<[/color] rho;
cout << "\nTheta is:\t" [color=red]<<[/color] theta [color=red]<<[/color] "radians or" [color=red]<<[/color] thetad [color=red]<<[/color] "degrees";
cout << "\n and Phi:\t" [color=red]<<[/color] phi [color=red]<<[/color] "radians or" [color=red]<<[/color] phid [color=red]<<[/color] "degrees.";
system("PAUSE");
return 0;
