Thread: File creating with string for name

I am trying to make a text editor using console and char array[100] strings.

If this isn't possible, tell me now My error code is as follows:

Code:

    char fileName[100];
    cout << "What do you want you're .editor to be today?\n";
    cin.getline ( fileName, 100, ' ');
    ofstream file(fileName ".editor");

The compiler error is 'expected ) before string constant'

Is it possible to use c style strings in this case?

I'd do it like this -

Code:

std::string NameOfFile;
std::cout<< "What do you want to call it: ";
std::cin >> NameOfFile;

// or std::getline( cin, NameOfFile );

ofstream out ( (NameOfFile + ".editor").c_str() );

// do stuff

out.close();

Yours doesn't work because

>> (fileName ".editor");

doesn't work. If you wish to remain with c style strings, instead of std::strings, use strcpy(), or strcat() or something. std::strings .c_str() returns a const char*, so it can be used for all sorts of things. They're great, research them, and you'll never use char*'s when there's a choice of use, IMO.

ofstream file(fileName ".editor");

I don't think this is legal
Try using strncat to append ".editor" to the end of filename, then try

Code:

ofstream file(filename);

or you can use strings instead of char arrays and just add the ".editor" to the end of the filename.

>ofstream file(fileName ".editor");
There's nothing between fileName and ".editor", which in this case is a syntax error. C-style strings are harder to work with. If you were using C++ strings then the fix would be as simple as:

Code:

ofstream file((fileName + ".editor").c_str());

But as it is, you need to concatenate ".editor" onto the end of fileName using something like strcat:

Code:

#include <cstring>

// ...

char fileName[100];

cout << "What do you want you're .editor to be today?\n";

// Leave room for the extension
if (cin.getline (fileName, 93, ' ')) {
  strcat(fileName, ".editor");

  ofstream file(fileName);

  // ...
}

Code:

#include <string>
#include <iostream>

using namespace std;

int main() {
    string str;
    cout<<"Enter a string : ";
    getline(cin, str);
    cout<<"\n" <<str;
    cin.get();
    return 0;
}

dang, I thought I edited that fast enough so no one would notice

You need a conditional statment to test if ToFile is a '1' or not, maybe something like this

Code:

while (true) {
    cout << "Type in your text, pressing 'enter' when finished with the line (typing 1 will end the loop and close your file): \n";
    getline(cin, toFile);
    if (toFile != "1")
        out << toFile;
    else
        break;
}
