Const in C++

Posted on One min read

From old CS271 notes…

Const pointers and data

T const *p; – p is a pointer to a const T (can be reversed: const T *p === T const *p)

T *const p; – p is a const pointer to T

T const *const p; – p is a const pointer to a const T

Const methods

Placing const after a method head and before the body means that it does not modify the object that it is called on.

Placing const in front of the return type means that the value returned cannot be modified.
