namespace
Syntax: namespace name {
declaration-list;
}
The namespace keyword allows you to create a new scope. The name is optional, and can be omitted to create an unnamed namespace. Once you create a namespace, you'll have to refer to it explicitly or use the using keyword. Example code:
namespace CartoonNameSpace {
int HomersAge;
void incrementHomersAge() {
HomersAge++;
}
}
int main() {
...
CartoonNameSpace::HomersAge = 39;
CartoonNameSpace::incrementHomersAge();
cout << CartoonNameSpace::HomersAge << endl;
...
}
