Vector : A vector is a container which performs like an extensible array. The size of the vector is dynamic. The series of elements are stored using the same variable name. It uses random-access iterator. If an element is added or removed, it adjusts its size automatically, which accommodates the number of elements contained in the vector.

Expert Solution & Answer

Explanation of Solution

Emplacement:

The technique used by member function to insert new elements in a container is emplacement. When new object is inserted into a container it avoids creation of temporary objects in memory.

emplace() and emplace_back() emplacement member functions:

Two member function in a vector class uses emplacement technique namely: “emplace()” and “emaplace_back()”.

These two member functions avoid the creation of memory when new object is inserted into a container.
There is no need to instantiate the objects which are going to be inserted.
The objects are just passed as an argument into the emplacement function.
The emplacement function handles the creation of object and then forwards to the argument to its constructor.

Comparing “emplace()” and “emplace_back()” member function with “insert()” and “push_back()” :

The “insert()” and “push_back()” member functions creates a temporary memory when new objects are inserted into a container.

Whereas, the “empalce” and “emplace_back()” member function avoids the creation of memory when new objects are inserted into a container.

You may use the vector and iostream libraries. You are allowed to use three built-in vector member functions (and no others) but you may not have to use them all. The member functions you are allowed to use are size(), at(), and push_back() Write a function that outputs a vector of doubles with each number in the vector separated by a space then a newline after the entire vector is output. The whole vector output should be preceded by a single line saying "Current Vector Contents:". Write a function that takes a vector a doubles and reverses the order of all the elements of the vector. Write a function that fills a vector of doubles with positive numbers using the standard input stream cin, terminate the input when the user enters any negative number. A single output prompt should precede the initial input stating directions for user. Write a main function that creates an empty vector, calls functions from 2 & 3 and calls your output function before and after each of your calls…

In this programming assignment, you will create a generic Vector class without using the utilities of the standard vector class and the template feature of C++. The design should allow its users to use an integer or character vector. You should review the standard vector class to learn what to include as data members and member functions.

create using c++ One problem with dynamic arrays is that once the array is created using the new operator the size cannot be changed. For example, you might want to add or delete entries from the array similar to the behavior of a vector . This project asks you to create a class called DynamicStringArray that includes member functions that allow it to emulate the behavior of a vector of strings. The class should have the following A private member variable called dynamicArray that references a dynamic array of type string. A private member variable called size that holds the number of entries in the array. A default constructor that sets the dynamic array to NULL and sets size to 0. A function that returns size . A function named addEntry that takes a string as input. The function should create a new dynamic array one element larger than dynamicArray , copy all elements from dynamicArray into the new array, add the new string onto the end of the new array, increment size, delete the…
