Question
What are using directives?
Answers
Whenever we want to make all the members of a namespace visible within a given program, we use a using directive. This gives a direction to the compiler that it has to look into this namespace for name resolution.
using namespace MySpace;
void main(){
cin >>FileName;
}
Here all the data members of the namespace MySpace are visible within the program.   Your Comment
