How do make a file with a custom name?

[Nitrosolid]

I want to be able to make a name of the file for my zip to cbr converter.

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main()
{
    string Dname="";

    cout << "Converter\n" << endl;

    cout << "Name of the file:";
    cin >> Dname;

    ofstream name;
    name.open (Dname".zip");

    cin.get();
}

[IceThatJaw]

name.open (Dname".zip");

This is no good. Ofsteam needs a cstring. It can either be in the full form "some_string" or it might be a std::string with a .c_std() method.

Like:
string std;

name.open(std.c_std());

@IceThatJaw,

I'm sorry to ask this, but isn't supposed to be .c_str()?

Um how do i make a zip extension? Also when i copy and paste to the console window it competently ignores the spaces and everything after it.Please help.

After you've read in the name of the file, you can use std::string's append() method to add ".zip". Then send Dname.c_str() to the filestream.

If you don't want to change Dname you can do
name.open((Dname + ".zip").c_str());

If you are using C++11 it's enough to do
name.open(Dname + ".zip");

Don't ask this, just correct me and move on.
I was close enough, right? haha

Right, it's because open is a member of ofstream and not string.
