Namespaces allow to group entities like classes, objects and functions under a name. This way the global scope can be divided in "sub-scopes", each one with its own name.The format of namespaces is:namespace identifier{entities}Where identifier is any valid identifier and entities is the set of classes, objects and functions that are included within the namespace. For example:namespace myNamespace{ int a, b;}In this case, the variables a and b are normal variables declared within a namespace called myNamespace. In order to access these variables from outside the myNamespace namespace we have to use the scope operator ::. For example, to access the previous variables from outside [myNamespace=] we can write:general::ageneral::b
It is the logical grouping of various similar classes !!! Why means that all the properties, fields and methos inside namespace are specific to this logical grouping ...
