- What is the difference between const int*, const int * const, and int . . .
const int* const is the same as int const* const and means "constant pointer to constant int" Edit: For the Dos and Don'ts, if this answer isn't enough, could you be more precise about what you want?
- Const in JavaScript: when to use it and is it necessary?
It then goes on to say: const is going to be defined by ECMAScript 6, but with different semantics Similar to variables declared with the let statement, constants declared with const will be block-scoped If you do use const you're going to have to add in a workaround to support slightly older browsers
- How do I best use the const keyword in C? - Stack Overflow
I am trying to get a sense of how I should use const in C code First I didn't really bother using it, but then I saw a quite a few examples of const being used throughout Should I make an effort
- What does the as const mean in TypeScript and what is its use case?
as const only affects the compiler, and there is an exception to its read-only effect (see the comments) But in general, that's still the major use difference between const and as const
- c - Constant pointer vs Pointer to constant - Stack Overflow
A constant pointer is declared as : int *const ptr ( the location of 'const' make the pointer 'ptr' as constant pointer) 2) Pointer to Constant : These type of pointers are the one which cannot change the value they are pointing to
- c - Difference between const const volatile - Stack Overflow
20 In C, const and volatile are type qualifiers and these two are independent Basically, const means that the value isn’t modifiable by the program And volatile means that the value is subject to sudden change (possibly from outside the program) In fact, the C Standard gives an example of a valid declaration which is both const and volatile
- c++ - What does `const T* const` mean? - Stack Overflow
This is a const pointer-to-const T So if T was an int, then array is a pointer to an int that is const in two ways: pointer-to-const: the value that the pointer is pointing to cannot be changed (or pointing to const int) const pointer: the memory address stored in the pointer cannot change This is also the same as T const * const array See wiki on const correctness
