1.   When does a name clash occur? Wipro

Answer:

            A name clash occurs when a name is defined in more than one place. For example., two different class libraries could give two different classes the same name. If you try to use many class libraries at the same time, there is a fair chance that you will be unable to compile or link the program because of name clashes.

2.   What is the use of ‘using’ declaration. WIPRO

Answer:

            A using declaration makes it possible to use a name from a namespace without the scope operator.
