Help needed about data input into a text file
I want to input data into text file while not deleting the original data in the file and I use something as
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

ofstream writefile;
writefile.open("example1.txt");
if (writefile.is_open())
{
for(j=0; j<N; j++)
{
writefile<<arrayQ[j][M-1];
writefile<<" ";
}
for(j=0; j<N; j++)
{
writefile<<arrayP[j][M-1];
writefile<<" ";
}
writefile.close();
}

But this will delete the original data. Anyone know how to solve this?
Open file in append mode ?
What do you mean by append mode? Can you give a sentence?
