vector.push_back

[collsion]

I have a private vector in Class A, after the constructor called, this vector is assigned because I put (for int i=0;i<vec.size( );i++) {cout<<vec[i]<<endl;} in side the constructor just to make sure vector is initilized and has size.
but when the accessor function is called, it seems that private vector is not assigned any value, the size is still 0. so what's going on? any help would be appreciated.

you have to explain you code more if you print the class or the part where the function is would be very helpful
but i think that you are not assigning any values to the vector
did you enter data into the vector so it could have a size and some values?
