Exception Handling in C. Also delete must be preferred if new used previously when the class has a non-default destructor to release the acquired resources. Like a constructor Destructor is also a member function of a class that has the same name as the class name preceded by a tilde operator.

In many cases dynamic allocation or resource acquisition during construction has a clean up phase. Add elements to the vector using push_back function 2. When a functions parameter type is of a class instead of passing a object to the function we can pass a braced-init-list to the function as the actual parameter.
