Thread: problem solved but is not accepted.

Hi there. I'm trying to solve this problem :
http://acm.uva.es/p/v111/11172.html
So i wrote this:

Code:

#include <fstream>
#include <iostream>
using namespace std;

int main()
{
	int pairs;
	int i, first, second;
	char pFirst[80], pSecond[80];
	char buffer[80];
    char szFile[80];

	cout << "Give the name of the file : " << endl;
	cin >> szFile;
	ifstream my_file(szFile);
    if(!my_file) {cerr<<"No such file"<<endl;getchar();exit(1);}
        my_file.getline(buffer,80);

        pairs=atoi(buffer);

	for(i=0;i<pairs;i++)
	{
		my_file.getline(pFirst,80,' ');
		my_file.getline(pSecond,80);

		first = atoi(pFirst);
		second = atoi(pSecond);

		if(first>second) cout << '>' << endl;
		else if(first<second) cout << '<' << endl;
		else cout << '=' << endl;
	}
    
    cin.get();
    return 0;
}

My code works fine (shows the correct results) both in VS 2005 and dev-C++. But, when I submited it to the uva, it was not accepted( had runtime or compilation error)

The weird thing about this problem is that although it needs to load a file as input,
(in uva) I am asked to upload only my code....

It's the first time I upload a code there and I'm a bit fuzzed. Can you please help me?

OK, if I understand right you mean , sth like this...

Code:

int main(int argc, char** argv);
{
....
ifstream my_file(argv[1]);
....
}
