Important Points about Constants
The following are some major properties of C++ constants discussed in the article:
- Constants are the variables with fixed values.
- We have to initialize the constants at the time of declaration and we cannot change this value later in the program.
- const and constexpr can be used to define a constant.
- #define is also used to define a macro constant.
