This variable is said to have file scope. Constant Variables. In C, the preprocessor directive #define was used to create a variable with a constant value. This still works in C++, but problems could arise. 2019-03-29 2005-11-15 #define GLOBAL_CONST_VAR 0xFF // this is C code not C++ int GLOBAL_CONST_VAR = 0xFF; // it is not constant and maybe not compilled Some function returing the value (e.g. int get_LOBAL_CONST_VAR()) // maybe but exists better desision enum { LOBAL_CONST_VAR = 0xFF; } // not needed, endeed, for only one constant (enum elms is a simple int, but with secial enumeration) const int GLOBAL_CONST_VAR = 0xFF; // it is the best extern const int GLOBAL_CONST_VAR; //some compiller doesn't understand this Which means we can access a global variable everywhere in same as well as other C programs (using extern). Example program to use global scope variables.

In C, static and global variables are initialized by the compiler itself. Therefore, they must be initialized with a constant value. Note that the above programs compile and run fine in C++, and produce the output as 10. As an exercise, predict the output of following program in both C and C++. Data type constants to be used in the ADD_FILTER or ADD_COLUMN procedures..

public class Constants. {. /// . Global Constants and Global Variables A constant which is needed in more than one functions can be declared a global constant by declaring it a constant using the reserve word const , initializing it and placing it outside of the body of all the functions, including the main function. A global static variable is one that can only be accessed in the file where it is created.

Headers may be used to declare globally used read-only resources, like string tables for example. I think that the best practise would be to make a class called, perhaps, 'Constants', which is solely a container for the constants. e.g.: ///

} class Program { static void Main() { double radius = 5.3; double area = Constants.Pi * (radius * radius); int secsFromSun = 149476000 / Constants.SpeedOfLight; // in km Console.WriteLine(secsFromSun); } } Global variables are variables whose scope is the entire program. That means that they must be defined outside any function, typically at the top of the program. Every function can access and change a global variable. Avoid using global variables without good reason. Constants are variables whose value cannot change.
