A simple question about variable

[Maer727]

- What does the following sentence mean? - Variable is a constant the compiler knows the value at compile time. - Can you show me an example? - Regards, Maer

couldn't it be the other way round: constant is a variable the compiler knows the value at compile time.. makes much more sense for me... bernhard

Variable is a constant the compiler knows the value at compile time Are you talking about const variables? Nish Sonork ID 100.9786 voidmain

- Where did this sentence come from? - It probably means that since the variable is declared "const", the compiler will know its exact value while it's compiling the file(s) that use it. Thus it can reliably use the variable for such things as allocating memory for arrays. - Example: const int MAX_ITEMS = 20; Item items[MAX_ITEMS]; - Regards, Alvaro

- I am talking about ordinary variables. - Regards, Maer

- Take a look at the following program: #include using namespace std; class a{ private: static const int s ; int i[s]; }; const int a:: s=20; void main() { cout<

- Thanks, Alvaro pal! - Take a look at the following program: #include using namespace std; class a{ private: static const int s ; int i[s]; }; const int a:: s=20; void main() { cout<
