Globals and namespace

[karmendra_js]

I am using some object refrence and boolean variables, these are declared golbally. I know this isn't a good practice but, it is required. I want to know Can i use nampespace to store these globals and is it of any importance. Also I don't know how to create and use namespace. Can you help me plz.

yes, you can put them in a namespace, and it's good style to do so. to declare:

namespace myNameSpace
{
bool globalBool;
CMyObject globalObject;
...
};

... to use:

myNameSpace::globalBool = false;

namespace MyNameSpace {
//declare here whatever you want...
}

Just a little addition to previous replies , if you don't want to write myNameSpace::SomeFunction() every time you call it, then you can add following line to your main() function : using namespace myNameSpace; And then you will be able to directly call SomeFunction() in main();

Hi, Yes you can locate global variables in namespaces. The importance of doing so depends on the specific case. For example, if you are afraid your var's name could conflict with another var's name, put yours in a namespace. Another example, if you have many global variables (hope you don't) you'd rather put them in a namespace in terms of 'well organization'. Code: namespace Globals { bool bVar1; bool bVar2; // any others... } // namespace Globals Now let's use it: // method 1. (not preferred) using namespace Globals; void f() { bVar1 = false; } // method 2. (less preferred) using Global::bVar1 void f() { bVar1 = false; } // method 3. (ok) void f() { Globals::bVar1 = false; }
