Vector Iterator: no match for ‘operator=’

Question

Considering the code C++ in the first code snippet below, I am getting the compilation errors indicated in the second snippet. It looks I am doing st wrong when traversing the vector instance. Can you tell me how I can overcome these compilation problems? Thanks. LINE 171 is marked in the code. SNIPPET 1 (Code) ``` #include #include #include class VipAddressSetEntity : BaseEntity { public: VipAddressSetEntity() : BaseEntity() { } VipAddressSetEntity(std::string &uuid, std::string &name) : BaseEntity(uuid, name) { } VipAddressSetEntity(const VipAddressSetEntity ©in) { setUUID(copyin.getUUID()); setName(copyin.getName()); std::vector::iterator iter; /* LINE 171 is the following*/ for( iter = copyin.mVipAddressList.begin(); iter != copyin.mVipAddressList.end(); iter++ ) { addVipAddress(*iter); } } VipAddressSetEntity operator = (const VipAddressSetEntity &rhs) { setUUID(rhs.getUUID()); setName(rhs.getName()); std::vector

Accepted Answer

`copyin` is a `const VipAddressSetEntity` and so `copyin.mVipAddressList` is also `const`. Calling `begin` on a `const std::vector` will give you an immutable iterator of type `std::vector::const_iterator`. Just make sure your `iter` is of that type too and you'll be able to assign to it just fine: ``` std::vector::const_iterator iter; ```
