Every data structure that we use in computer science has its weaknesses and strengthsHaving a full understanding of each will help make us better programmers!For this experiment, let's work with STL vectors and STL dequesFull requirements descriptions are found in the source code file Part 1Work with inserting elements at the front of a vector and a deque (30%) Part 2Work with inserting elements at the back of a vector and a deque (30%) Part 3Work with inserting elements in the middle, and removing elements from, a vector and a deque (40%) Please make sure to put your code specifically where it is asked for, and no where elseDo not modify any of the code you already see in the template file This C++ source code file is required to complete this problem
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…

Q/ write Matlab code that asks the user to enter several (elements (N) in Vector (V) -: uses (input) then ask the user to enter the values of elements of the vector: use (inputting) Note 1. Write the code in the matlab 2. Complete the execution and take pictures of the execution 3. Type (or copy and paste the code in the window for the problem one here
in c++ Write a function named “getLowest” that accepts a vector of pointers to Student objects. It will go through the list and return pointers to the Student or GradStudent with the lowest student ID and GPA. Please note that the vector contains pointers to either Student or GradStudent objects. Please show that you have tested with a vector of pointers of mixed Student and GradStudent objects (in the same vector) For example, if these students and grad students are in the list Student(2000, "John Smith", 4.0) GradStudent(3000,"Nancy Brown", 3.5, 2021) ; Student(1000, "Bob Johnson", 3.0) ; GradStudent(4000, "Tim Jackson", 2.0, 2020)) ; It will return pointers to these two objects: Lowest ID: ID(1000) NAME(Bob Johnson) GPA(3.00) Lowest GPA: ID(4000) NAME(Tim Jackson) GPA(2.00) GRADUATION-YEAR(2020)
C++.Write a function, named SecondNegative, that takes a const reference to a vector of doubles, it should return an const_iterator to the element in the vector that is the second value that is negative. If no such element exists, have the iterator point to one past the end.
In c++ please Write the RemoveEvens() function, which receives a vector of integers as a parameter and returns a new vector of integers containing only the odd numbers from the original vector. The main program outputs values of the returned vector. Hint: If the original vector has even numbers, then the new vector will be smaller in length than the original vector and should have no blank element. Ex: If the vector passed to the RemoveEvens() function is [1, 2, 3, 4, 5, 6, 7, 8, 9], then the function returns and the program output is: [1, 3, 5, 7, 9] Ex: If the vector passed to the RemoveEvens() function is [1, 9, 3], hen the function returns and the program output is: [1, 9, 3] #include <iostream>#include <vector>using namespace std; vector<int> RemoveEvens(vector<int> nums) { /* Type your code here */} int main() { vector<int> input(9); input.at(0) = 1; input.at(1) = 2; input.at(2) = 3; input.at(3) = 4; input.at(4) = 5;…
