Anyone knows how to open a text file and write the content of it to a text file with command line or arguments, i mean using the argc and argv.

thanx for answer!

using namespace std;
int main(int argc,char* argv[])
string input;
cout<<"Enter a command line argument!!"<<endl;
return 1;
ofstream fout("new.txt");
cout<<"Enter some text to the file..";
ifstream fin("new.txt");
cout<<"Unable to open file!!"<<endl;
return 1;
return 0;

The executable of this code can only work if some command-line arguments are added.
Hope this helped!!(Pls, you would show your appreciation by adding to my reputation)

int main(int argc, char*argv[])
   ofstream out;
   if( argc == 2)
       if( !out.is_open())
           cout << "Failed to open the file \"" << argv[1] << "\"\n";
           return 1;
        cout << "usage: myprog filename\n";
        return 1`;
   // now write to the file
