Hi,
I recently bought shared hosting. Now, I have little problem. Could you help me please? I am having a problem in reading a file i tried my code in code blocks/eclipse c++/netbeans c++ and even visual studio c++ 2010
each time it exits with (-1) while i'm puting the file in the right place for reading i don't know where is the mistake can you please help me
here's the file that i'm trying to read Problem.dat_50_50_0
here's my code:

Code:
#include <iostream>
#include <fstream>
#include <vector>
#include <stdlib.h>
using namespace std;
int main(int argc, char **argv) {
    ifstream inFile;
    inFile.open("Problem.dat_50_50_0");
    if ( !inFile ) {
        cout << "the file could not be opened!" << endl;
        exit(-1);
    }
    string line;
    int n, value;
    vector<int> w;
    inFile >> n;
    for ( int i = 0; i < n; ++i)
        if ( inFile >> value )
            w.push_back(value);
    vector<vector<int> > matrix(n , vector<int>(n));
    vector<vector<int> > adj(n);
    for (int i = 0; i < n; ++i) {
        cout << w.at(i) << ", ";
    }
    cout << endl;
    for (int i = 0; i < n; ++i) {
        for (int j = 0; j < n; ++j) {
            inFile >> value;
            matrix.at(i).at(j) = value;
            if (value == 1)
                adj.at(i).push_back(j);
        }
    }
    for (int i = 0; i < adj.size(); ++i) {
        cout << "[" << i << "]: ";
        for (int j = 0; j < adj.at(i).size(); ++j) {
            cout << adj.at(i).at(j) << ",";
        }
        cout << endl;
    }
    return 0;
}
