noexcept
1)noexcept specifier:
This means if a function specified with noexcept it shouldn't throw exeption.
In the case of excpetion std::sterminate will be called

2)noexcept operator
It tests if a function noexcept specification evalute to true or false at
complie time. noexcept(some compile time expression) and this returns a boolan



when should we use it?
1)When using c++ functions in c
2)when c++ standard requires us.
