Problem with generate two txt file in one program

[qingze]

I try to write my data into two different files and i just use something like this

ofstream myfile;
myfile.open("phase 1.txt");
if (myfile.is_open())
{
	for(i=0;i<M; i++)
	{
       	    myfile<<arrayD[j][10*i];
	    myfile<<",";	   
   	}
	return 0;  
        myfile.close();
}
ofstream myfile1;
myfile1.open("phase 2.txt");
if (myfile1.is_open())
{
	for(i=0;i<M; i++)
	{
       	    myfile1<<arrayD[j][10*i];
	    myfile1<<",";	   
   	}
	return 0;  
        myfile1.close();
}

But it only generate the first file. Anyone know the reason, how should i modify this? Any help is appreciated.

I think you don't need the

ofstream myfile1

just re-use myfile

still only generate 1 file...

[greenleaf800073]

do you have #include <fstream>?

you should also do

myfile.open("phase 1.txt", fstream::in | fstream::app);
