Write a file in a specific path in C++

Question

I have this code that writes successfully a file:

    ofstream outfile (path);
    outfile.write(buffer,size);
    outfile.flush();
    outfile.close();
         


        

Answer 1

I was stuck on this for a while and have since figured it out. The path is based off where your executable is and varies a little. For this example assume you do a ls while in your executable directory and see:

myprogram.out  Saves  

Where Saves is a folder and myprogram.out is the program you are running.

In your code, if you are converting chars to a c_str() in a manner like this:

string file;
getline(cin, file, '\n');
ifstream thefile;
thefile.open( ("Saves/" + file + ".txt").c_str() );

and the user types in savefile, it would be

"Saves/savefile.txt"   

which will work to get to to get to savefile.txt in your Saves folder. Notice there is no pre-slashes and you just start with the folder name.

However if you are using a string literal like

ifstream thefile;
thefile.open("./Saves/savefile.txt");

it would be like this to get to the same folder:

"./Saves/savefile.txt"  

Notice you start with a ./ in front of the foldername.
