Some points to note about C++ vector: *It is a dynamic container which provides a fast and efficient way to

In C++ vector also support the operator[](uses the subscript ‘[ ]’) which allow access of the element in any position

The C++ vector max_size function returns the maximum number of elements the vector can hold. size_t max_size( ) const; Parameters:

The C++ vector size function returns the number of elements held by the vector currently. size_t size( ) const ;

The C++ vector pop_back function of vector removes the last element of the vector. void pop_back(); Parameters: none Return type

The C++ vector begin( ) function returns an iterator that points to the first element in the vector. iterator begin();

The C++ vector swap function swap the two vectors data. void swap(vector& x); Parameters: x – A vector whose data

The C++ vector data() function returns a pointer to the vector element.There are two types of data() function. T :type

The C++ vector emplace_back function like the push_back function append data at the end of the vector.It is added in

In this post we will discuss the difference between push_back and emplace_back function in C++. Although C++ emplace_back and push_back
