Operations of vector class

The vector class is available in Java and C++ programming languages. It is a class implementing a dynamic array. A dynamic array is an array whose size automatically increases when an element is added to it. The vector class stores elements in a contiguous memory block and assigns the memory to the elements whenever required during execution.
