Data management

[Alexanov]

Hi
I wrote a code to create QByteArray like this:

QByteArray qbDatagram;
    for(int i = 8019; i >=0;i--)
    {
        qbDatagram[i] =i;
    }

Then I want to put 10e7 (10 Million ) qbDatagram packet side by side, like below:

for (int l=10000000; l>0,l--){
varaiable or object or ... = + qbDatagram;
}

qbDatagram(8019)+qbDatagram(8019)+..10M..+qbDatagram(8019)
But i don't know how ? and with which type of var or object or ... we can support to save huge data in it?
QByteArray alone support 2GB capacity.
