Program won't compile..

[ADTR2012]

Im getting a linker error:
Error 2 error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup
Error 3 error LNK1120: 1 unresolved externals

How can I fix this? Here's my code..

#ifndef BIGINT_H
#define BIGINT_H

const int MAXINT = 500;

class bigint{
	public:
		bigint();
		bigint(int);
		bigint(char[]);
		void output (std::ostream& out);
		bool compare(const bigint &rhs);

	private:
		int value[MAXINT];
};

#endif 

#include <iostream>
#include "bigint.h"

bigint::bigint(){
	
	for(int i=0; i <= MAXINT; i++)
		value[i] = 0;
}

bigint::bigint(int digit){

	int numdigits = log10((double)digit) + 1;

	for (int i=numdigits-1; i >= 0; i--)
	{
		value[i] = digit%10;
		digit /= 10;
	}
}

bigint::bigint(char *number){
	
	for (int i=0; i <= MAXINT; i++){
		number[i] =- '0';
		number[i] = value[i];
	}
}

void bigint::output(std::ostream& o){

	for(int i=0; i <= MAXINT; i++)
		std::cout << value [i];
}

bool bigint::compare(const bigint &rhs){

	bool comp;

	for(int i=0; i <= MAXINT; i++){
		if(value[i] == rhs.value[i])
			comp = true;
	}
	return comp;
}

You are missing a main() function.

Why were you reported??

@Superdude, check the forum, in the last 12hrs --how many posts(of the same type) has he posted? Over 5, I could count! Same thing over and over and over
