flush the stream

[Someonekicked]

hi, i cant come to find a solution for a problem in my program, I made an
example of the problem;
in the example i made, the problem is if happy.dat does not exist, so
(!inData) will be true, and "here is the message" is sent to output to
happy.dat, and if u run the program, you will see that "here is the message"
is sent to happy.dat after the program ends, not be4 cout << "check"; i want
that "here is the message" be sent to file be4 seeing "check".
thx in advance for any suggestions , ive been struggling with this for long,
nothing i tried worked.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
string lol = "happy.dat" ;
ifstream inData;
ofstream outData;
inData.open(lol .c_str());
if (!inData)
{
outData.open(lo l.c_str());
string message = "here is the message";
outData << message ;
}
cout << "check" << endl;
int check;
cin >> check;
return 0;
}

string message = "here is the message";
outData << message ;
Try adding

outData << flush;
outData.close() ;

although the effect is probably still platform-specific.
}
cout << "check" << endl;
int check;
cin >> check;
return 0;

either, anyway, thx a lot !
