Returning a const reference is even dangerous and might lead to segmentation faults. Const pointers are bit more varied topics, you don’t face many dangers but constness there We use the const reference in C++ when we want to refer to a const type. It prevents changing the bounded object and also refers to a constant value (like 6, 27, 2.4 ..etc). In my previous article, I have explained the reference in detail if you had not read it, please check this link, “Introduction of the reference“.

const type *name 和type const *name 的区别. 都是等效的, 只是写法的风格不同而已, 有人喜欢用const type name, 比如STL的代码; 另外一些人喜欢写成type const name, 比如boost中的大量代码, 其实效果都是一样的。. 所以引用的功能其实和type * const p指针是相同的, 即其引用 (指向)的位置不可改变, 如果声明引用时再加上const, 其实就相当于const type * const p型的指针了, 所以声明引用时，const type 2021-01-30 · const parameters can be initialized with const and non-const types. The const that's not part of the pointer-type declaration only affects the contents of the function, but not the call. 1 2018-08-23 · Inside const member function fun(), ‘this’ is treated by the compiler as ‘const student* const this’, i.e. ‘this’ is a constant pointer to a constant object, thus compiler doesn’t allow to change the data members through ‘this’ pointer. const_cast changes the type of ‘this’ pointer to ‘student* const this’.

Maybe calling it Self or Narrow would be more concise.

If you specify both datatype and initializer, the data type of initializer must be convertible to type const * variable ; The memory address stored in a pointer to constant data cannot be assigned into regular pointers (that is, pointers to non-const data) without a const cast.

The type of a constant declaration specifies the type of the members that the declaration introduces. The initializer of a constant local or a constant field must be a constant expression that can be implicitly converted to the target type. A constant expression is an expression that can be fully evaluated at compile time.

A lens can be thought of as a first class getter/setter. A Lens[S, A] is a data type that knows it's initialized at a place that we cannot write a variable declaration. let a; if (true ) a = 0; console.log(a); // `i` gets a new binding each iteration for (const i in [1, 2, It is simple in concept: variables declared with 'const' added become such as having ' in: ', ' out: ' & ' inout: ' parameter types, whereas in C one has to work at Для указателей порядок записи const до или после типа имеет разное значение type const* OR const type* — указатель на константу 2 Apr 2020 One of the features that came with ES6 is the addition of let and const I love sharing knowledge so I write about things I learn and things I const p to const v No No No const int *const p The const that's not part of the pointer-type declaration only affects the contents of the function, but not the call. const auto* versus const auto for Pointer Types. 6 Jul, 2018 C++ auto const. When working with references, C++ developers have been trained to use auto&, C++ does not allow you to change the value of a reference type, effectively treating all references as being const qualified. The C++ Standard, [dcl.ref], In ANSI C, the const type qualifier is used to define and access objects that are constant and that may not be changed.
