I encountered this problem maintaining a port for a large (relative to the size of our team) project, but it was simple to create a small example. stackoverflow.cpp: #include<iostream> #include&...

The following doesn't compile (very verbose error, but basically "cannot be overloaded" and "invalid conversion from 'const void*' to 'void*'"). I can understand why for example push_back() may not ...

push_backing to a vector of non-const elements works as expected: std::vector<int> foo; int bar = 0; foo.push_back(bar); But why is the following not possible? std::vector<const int> foo;...

What is the rationale behind C++11 forbidding containers of const elements? I am referring to the following error message, which you get if you define, for example, a vector of const elements: error ...

As this answer said: The component type of containers like vectors must be assignable. References are not assignable (you can only initialize them once when they are declared, and you cannot make ...

I want to make a vector of const pointers. (the pointers being constant, not A being constant) This code here gives me the error: class A{}; std::vector<A * const> vec; //creates vector of ...

First of all: I'm still a beginner in c ++, but I don't really understand the following: So someone said to me, that if i have for example a container of references (e.g. map), it is not working ...

The standard library vector prevents us from constructing a vector of consts. My question is why? I read the answers on apparently similar questions to mine and I'm not really convinced. So let's dig ...

I have a class with std::set<const std::string> members which compiles fine in Clang 10.0.1 on macOS, but does not with GCC 5.4.0. MRE below #include <set> #include <string> class ...

vector<const int>() fails to compile in C++14 (and in C++03). Under C++03, we can say const int is not CopyAssignable, so naturally it fails. However, under C++14, the wording in the standard ...

Does const vector<A> mean that its elements are constas well? In the code below, v[0].set (1234); in void g ( const vector<A> & v ) produces the compiler error const.cpp:28:3: ...

I have declared the following in my code vector <const A> mylist; I get the following compile error - new_allocator.h:75: error: `const _Tp* __gnu_cxx::new_allocator<_Tp>::address(...

See the code below - I am trying to put a const object into a vector. I know the answer is "STL containers require objects to be assignable and copy constructable", but, without citing the standard, ...

After scratching my head at some errors in some template code that used std::vector::value_type I tracked it down to the following. Is this correct behavior according to the standard, or is this a ...

It seems to me there should be four variants of boost::optional optional<Foo> => holds a mutable Foo and can be reassigned after initialization optional<Foo const> const => holds a const ...
