Good morning to all!
I'm a C++ new-newbie... and I have a problem
i' ve to manage an array of vector:

int NumCols=1;
vector<int> a[NumCols];

then i should initialize the first (and at all, only) element of the fisrt vector with 0 value.
and so i write:


But this give me an error
Error: non class,struct,union object a[0] used with . or -> FILE:L.C LINE:165

Could you give me some hint?

After this i have to increment NumCols (in a cycle when some conditions are satisfied):

for (i=1; i<jet.size(); i++){
for (int cols=0; cols<NumCols; cols++){
CalculateDR(jet[i], jet[a[cols].front()]);

if (DR> DRref){

if (DR <= DRref){

as i ve already wrote, i m a newbie and so i suppose that there are many errors.....

Thanks to all!
