and initializing variables: Declare variables using this format: type variable name = initial value; /* descriptivecomment*/ Declare all variables used within business functionsand internal functions at the beginning of the function. AlthoughC allows you to declare variables within compound ...
DECLARE vSiteID CONSTANT integer := 50; This would declare a constant calledvSiteIDas an integer data type and assign an initial value of 50. Because this variable is declared using the CONSTANT keyword, you can not change its value after initializing the variable....
You have the choice of specifying a starting value, and if this is not specified, the compiler evaluates it to 0. So, North is evaluated as value 0. If you want, you can also specify an explicit value against each of the enumerated constants by initializing them. Listing 3.9 demonstrates...

In the above code, we created a function named "Double" that involves initializing two variables and multiplying them by two. Later, these variables are used in the main function using the out parameter. The values of these variables are doubled and then displayed in the output using the pri...
In C++, the const keyword can be used with variables, pointers, function arguments, class data members, and class objects to indicate that their values or state cannot be modified. This improves the safety and reliability of C++ code by preventing inadvertent modification of important data. ...
constructor,destructor,used,unused,deprecated,weak,malloc,alias,warn_unused_resultandnonnull. Several other attributes are defined for functions on particular target systems. Other attributes, includingsectionare supported for variables declarations (seeVariable Attributes) and for types (seeType Attributes)....
The class body (the area between the braces) contains all the code that provides for the life cycle of the objects created from the class: constructors for initializing new objects, declarations for the fields that provide the state of the class and its objects, and methods to implement the...
