Q1. Use of namespace in c++
Ans. 
Namespace in C++ is used to avoid naming conflicts and organize code.

• It helps in avoiding naming conflicts by providing a unique identifier to each entity.

• Namespace can be nested within another namespace.

Q2. How would++(++i) work
Ans. 
The expression would increment the value of i twice before using it in the operation.
• The value of i would be incremented by 2 before being used in the operation.

• This is equivalent to writing i = i + 2; followed by the operation using the new value of i.

• For example, if i was initially 3, the expression would evaluate to 6.
