Constant Contact Issues Constant Pointers Lets first understand what a constant pointer is A constant pointer is a pointer that cannot change the address its holding In other words we can say that once a constant pointer points to a variable then it cannot point to any other variable A constant pointer is declared as follows const
The recommended naming and capitalization convention is to use P ascal C asing for constants Microsoft has a tool named StyleCop that documents all the preferred conventions and can check your source for compliance though it is a little bit too anally retentive for many people s tastes e g private const int TheAnswer 42 The Pascal capitalization convention is also How do I declare a constant in Python In Java we do public static final String CONST NAME Name

DECLARE Constant INT 123 SELECT FROM some relation WHERE some attribute Constant OPTION OPTIMIZE FOR Constant 123 This tells the query compiler to treat the variable as if it was a constant when creating the execution plan The down side is that you have to define the value twice What is the difference between static const and const For example static const int a 5 const int i 5 Is there any difference between them When would you use one over the other
Moreover in C language the term constant refers to literal constants like 1 a 0xFF and so on enum members and results of such operators as sizeof Const qualified objects of any type are not constants in C language terminology They cannot be used in initializers of objects with static storage duration regardless of their type Exception a starting const applies to what follows const int is the same as int const and means pointer to constant 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
