write to file multiple times

[eliranko]

hello,
I have a problem with writing to the same file in seperate cases.

I opened a file

ofstream myfileRandom("random.log");
    if(myfileRandom.is_open())
    	myfileRandom.close();

and after some code , I wrote to the file:

myfileRandom.open("random.log");
myfileRandom <<""bla bla<<endl;
myfileRandom.close();

every time I write to the file it deletes my previous data.
how can I write to file without deleting previous data?

Thnx alot!

myfileRandom.open("random.log", ios::ate);

what peter said, or don't close the file until the end of your program.

ios::app -- Append to the file
ios::ate -- Set the current position to the end
ios::trunc -- Delete everything in the file
