c++ - Vector and assignment operator -

i need deep copy of vector vector. ex -

vector<char> a; // add things vector<char> b;  = b; 

i know can a(b) problem must reassign more once , global variable, i'm pretty sure can't use copy constructor once it's created. assignment operator overloaded vector, if not best way copy vector , members.

yes, assignment operator overloaded std::vector , can safely use a = b;
