Jul 24, 2015 When I read "static inline", it doesn't look at all like something meaning "const" other than by accident of the history of the compiler/syntax.

const 선언은 블록 범위의 상수를 선언합니다. 상수의 값은 재할당할 수 없으며 다시 선언할 수도 없습니다. This antipattern keeps coming up, so here’s the blog post I can point people to. Today we’re talking about const_iterator. First of all — you know this — const_iterator is different from iterator const, in exactly the same way that const int * is different from int *const. The const keyword is used to declare those properties which are immutable in nature i.e.

'Const' allows for declaration once and for assignment once, and can never be re-declared or reassigned (block-scoped). For instance, I use 'const' for inline function declarations, so that I don't accidentally redefine this function's behavior at some later point in time by mistake.
Because of this, we cannot change constant primitive values, but we can change the properties of constant objects.
Let’s dig deeper. We can declare constant variables (or more…

The const keyword is used to declare those properties which are immutable in nature i.e. these properties are read-only properties. But, the value of these properties must be known at the compile-time only and this is the reason const is also known as Compile-time constant. So, no runtime assignment of values is allowed in const variables.

"const X* or X const*" means you cannot change the object that is being pointed at the moment, but you can make the pointer point … // You can create a const object: const car = {type:"Fiat", model:"500", color:"white"}; // You can change a property: car.color = "red"; // You can add a property: car.owner = "Johnson"; This behavior is somehow different when it comes to objects declared with const.

"const X* or X const*" means you cannot change the object that is being pointed at the moment, but you can make the pointer point … // You can create a const object: const car = {type:"Fiat", model:"500", color:"white"}; // You can change a property: car.color = "red"; // You can add a property: car.owner = "Johnson"; This behavior is somehow different when it comes to objects declared with const. While a const object cannot be updated, the properties of this objects can be updated. Therefore, if we declare a const object as this: const greeting = { message: "say Hi", times: 4 } while we cannot do this: const is pointless when the argument is passed by value since you will not be modifying the caller's object.
