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’. 2021-03-15 · In this article, the various functions of the const keyword which is found in C++ are discussed.

2012-08-13 How is “const correctness” related to ordinary type safety? Declaring the const-ness of a parameter is just another form of type safety.


Eq Term Source #.

In the C, C++, D, JavaScript and Julia programming languages, const is a type qualifier: a keyword applied to a data type that indicates that the data is read only. While this can be used to declare constants, const in the C family of languages differs from similar constructs in other languages in being part of the type, and thus has complicated behavior when combined with pointers, references, composite data types, and type-checking. Se hela listan på When declaring a const variable, it is possible to put const either before or after the type: that is, both int const x = 5; and const int x = 4; result in x's being a constant integer. Note that in both cases, the value of the variable is specified in the declaration; there's no way to set it later!
