Compiler is convinced my main is a header file

[Gunnir]

I've done something silly, probably throughout here, that has made my compiler think that my main code (pasted below) is a class. I dont know what i've done wrong. Here is the code:

#include <iostream>
#include <fstream>                      // Relevant libraries and particle header called
#include <cstdlib>
#include <cmath>

#include "detector.h"
#include "/Users/Vito/Documents/Section 4/Section 4/particleclass.h"

using namespace std;

int main()
{
    ofstream positronfile("/Users/Vito/Documents/Section 5/Section 5/positron_Ek.txt"),
    muonfile("/Users/Vito/Documents/Section 5/Section 5/muon_Ek.txt"),
    michelfile("/Users/Vito/Documents/Section 5/Section 5/michel_Ek.txt");
    
    
    // Initialising particles
    particle muon (105.7, 0, 0, 29.78), positron (0.511, 0, 0, 69.80);
    
    
    // Distribution for perfect detector, 1000 muons and positrons
    particle marr[1000], parr[1000];
    for (int j = 0; j <= 999; j++)    // For-loop that fills all 1000 particle array slots generated
    {
        threevector m_rand (muon.mag(), random_theta(), random_phi(), 'r'),    // Particle position
        p_rand (positron.mag(), random_theta(), random_phi(), 'r');
        
        marr[j] = particle (105.7, m_rand);         // Assigning the array of particles
        parr[j] = particle (0.511, p_rand);
        
        muonfile << marr[j].Ek() <<'\t'<< m_rand.gettheta() <<'\t'<< m_rand.getphi() << endl;
        positronfile <<parr[j].Ek()<<'\t'<< p_rand.gettheta()<<'\t'<< p_rand.getphi() << endl;
    }
    
    
    // Michel distribution for 1000 positrons (muon decay)
    particle michel_parr[1000];
    for (int j = 0; j <= 999; j++)
    {
        threevector p_michel (michel(), random_theta(), random_phi(), 'r');     // Position, again
        
        michel_parr[j] = particle(0.511, p_michel);      // Assiging the particles to the array
        
        michelfile << michel_parr[j].Ek() <<'\t'        // Find theta at each array location
        << michel_parr[j].gettheta() <<'\t'  // NOTE: still works, *exactly*, if you use
        << michel_parr[j].getphi() << endl;  //  p_michel rather than michel_parr
    }
    
    
    // Using acceptance
    
    particle accept_marr[1000], accept_parr[1000];
    detector measure (40, 140, 'd');
    double pcounter = 0.0, mcounter = 0.0; // Counter for pion decay and muon decay
    
    
    for (int j = 0; j <= 999; j++)
    {
        cout << measure.getEk(parr[j]) << endl;
        if(measure.getEk(parr[j])) // If Ek is in direction limits, returns Ek
        {
            mcounter += mcounter;
        }
        
        //cout << measure.getEk(michel_parr[j]) << endl;
        if(measure.getEk(michel_parr[j]) > 0.0) // Muon decay particle energy
        {
            pcounter += pcounter;
        }
        
    }
    return 0;
}


// Custom function declarations
double michel()                     // Creating the michel function
{
    double x, y;
    do
    {
        x = 53.0*rand()/RAND_MAX;
        y = x/53.0;
    }
    while (1.0*rand()/RAND_MAX > y);
    return x;
}

double random_theta()               // Creating a random theta function
{
    double x = acos((1.0*rand()/RAND_MAX - 0.5)*2.0); // Generates random No. between -1 and 1
    return x;                                        //  acos() then translates into 0 -> pi
}
double random_phi()                 // Creating a random phi function, can call both later
{
    double x = (1.0*rand()/RAND_MAX - 0.5)*8.0*atan(1.0); //Pi*random No. (-1 to 1) (i.e. phi range)
    return x;
}

Since you didn't post detector.h, particleclass.h, or the actual error message, it is hard to tell.

Offhand, I suggest looking for a missing semicolon at the end of one of your class declarations.

[Gunnir]

i'll screen my classes, thank you, and here are some of the error messages:

" 'using namespace' is not allowed in classes", this is on line 9

Errors on line with endl; and cout involve unclear identifiers, wants me to use std::endl and std::cout etc

Final error on the last line, 99, expecting a ; for the end of the class

Look in your header file and check to make sure your classes have semicolons after the closing }, like AbstractionAnon said.

I'm a moron!!!

I forgot to put the semi colon at the end of my class detector.h, thank you very much AbstractionAnon!

I'll keep the thread open in case I come across anything else silly
Thanks again
