When I use the resize function, it doesnt do it right.
it should add this (211210999999788789) at the end, but it doesnt. there are just some ramdom o letter with a line on top.
Does anyone know how to fix this?
I tryed changing aa to a string, but it gave me an error, aying that you can insert a string into the resize function.

Keyn is a user input.
Outputn is the Output.

int nine(999999);
unsigned long long aa;
unsigned long long keyn;
string outputn;
    
    std::cin >> keyn << endl;
    aa = nine * keyn;                                                                               
    outputn.resize(80, aa);
    std::cout << outputn;

Thankyou.
