Error: expected constructor, destructor

[ShoxPhysics]

Hello, when I go to compile my code I keep returning the following errors:
41: error: expected ‘;’ before ‘}’ token
43: error: expected constructor, destructor, or type conversion before ‘=’ token [multiple occurances of this- lines 44, 48,49,54,55,60,61 ]
63: error: expected constructor, destructor, or type conversion before ‘<<’ token
66:error: expected constructor, destructor, or type conversion before ‘.’ token

Somebody please help, because I have never seen this error before and can't see what I am doing wrong.

Don't just read the error messages, inspect them.

You had an extra } token that ended main before return 0; This is why I use this style:

if (something)
{
}

Here's your code. Also, I think we shouldn't use *.h lib files, but instead c* as in cmath instead of math.h

#include <cstdio>
#include <iostream>
#include <cmath>
#include <fstream>
#include <cstdlib>
using namespace std;

#define PI 3.141592

//r=a+e(r*cos(p))
//find a and e using method of least squares

int main() {
 double r[50],phi[50],rphi[50],ravg,rphiavg,a,e,cov,v;
 int j,k;
 ifstream orbitdata;

 orbitdata.open ("orbits.dat");
  if (!orbitdata) {
 cerr<< "error:file will not open"<< endl;
 exit(1);
 }

 k=0;
 orbitdata >> phi[0] >> r[0];
 while (orbitdata.good()){
   k++;
   orbitdata >> phi[k] >> r[k];
 }

 for (j=0;j<k;j++) {
  rphi[j]=r[j]*cos(PI*phi[j]/180.);
    //     cout << phi[j] << " "<< r[j]<<"\n';
  }

 ravg=0;
 rphiavg=0;
 // cout << rphiavg << "\n" ;


 ravg=ravg/ ( double ) k;
 rphiavg=rphiavg/ ( double ) k;

 // cout << ravg << "\n" << rphiavg << "\n";

 cov=0;
 v=0;
 for (j=0; j<k;j++){
  v=v+(rphi[j]-rphiavg)*(rphi[j]-rphiavg);
  cov=cov+(rphi[j]-rphiavg)*(r[j]-ravg);}

 cov=cov/(j);
 v=v/(j);

 //cout << "v =" << v<< "\n";
 //cout << "cov = " << cov << "\n";

 e=cov/v;
 a=ravg-e*rphiavg;

 cout << "e = " << e << "\n";
 cout << "a = " << a << "\n";

 orbitdata.close();
 return 0;
}

thank you, I just needed a fresh pair of eyes to look at it. I will take your suggestion into account.
