#include <iostream>
#include <fstream>
using namespace std;
int write();
int main() {
write();
cout << "Contents written to file\n";
cin.get();
return 0;
}
int write() {
ofstream log;
log.open("log.txt", ios::ate);
log << "File Opened";
log.close();
return 0;
}
What am i missing? I just want this code to post everytime i run it "File opened" in the file. Currently it posts it once and everytime i run the program it just has it once printed in the file. I want it to keep printing to the end of the file....

Need help with this code:
log.open("log.txt", ios::ate);You should use "source", rather than "code", for your tags to get a code block.
As to your problem, I'm not exactly certain I understand what you want to do. Do you want to keep adding a line of text to the end of the existing file each time?
If so, you probably want to use ios::app rather than ios:ate.
Try this page for a more details look at reading/writing files in C++.

Also, the board markup [something_in_here] tags all use lowercase.
Anyway, things can and should be made much simpler, but yeah, the basic point is that you probably want the ios::app flag instead.

#include <iostream>#include <fstream>using namespace std;void write() { ofstream("log.txt", ios::app) << "File Opened";}int main() { write(); cout << "Contents written to file\n";}
Check to see if the ofstream is successful:
