Write a C++ program as follows: Declare 2 empty vectors of integers named vector1 and vector 2, respectively. Add 10 and 20 to vector1 dynamically using push_back Display the elements in vector1 using the at() method as well as its size using the size() metho Add 100 and 200 to vector2 dynamically using push_back Display the elements in vector2 using the at() method as well as its size using the size() metho Declare an empty 2D vector called vector_2d Remember, that a 2D vector is a vector of vector Add vector1 to vector_2d dyanmically using push_back Add vector2 to vector_2d dynamically using push_back Display the elements in vector_2d using the at() method Change vector1.at(0) to 1000 Display the elements in vector_2d again using the at() method Display the elements in vector1 What did you expect? Did you get what you expected? What do you think happended?

In PYTHON  Define a vector of integers with 5 elements  Write the following function  Given a vector and two indexes, returns a vector where the values at the provided indexes are swapped  Example Input: my_vector = [40,51,62,73,84,95]  Invokefunction:swap(my_vector,2,4)  Output:[40,51,84,73,62,95]

Programing language is C

Python numpy library functions to perform basic matrix operations are as follows.• C=numpy.add(A, B): Add two matrices A and B and store result in C.• C=numpy.subtract(A, B): Subtract matrix B from matrix A and store result in C.• C=numpy.divide(A, B): Divide matrix A by matrix B and store result in C.• C=numpy.multiply(A, B): Multiply matrix A by matrix B and store result in C.• C=numpy.sum(A): Form the sum of elements of matrix A and store result in c ∈ R.• C=numpy.sum(A, axis = 0): Form the column wise summation of matrix A andstore result in vector C.• C=numpy.sum(A, axis = 1): Form the row wise summation of matrix A, storeresult in vector C.Python code to show the implementation of these methods in a sample matrix.

What performance advantages do vectors provide over arrays?

WRITE A PROGRAM IN C++ You work for an loan analytics organization have been tasked with writing a program that simulates an analysis of loan applications. Code a modular program that uses parallel arrays to store loan application credit scores (values generated between 300 and 900), score ratings (poor, fair, good, very good, or exceptional based on credit score) and loan status (approved or declined applications based on credit score). The program must do the following: The program must first ask the user for the number of loan applications that will be in the simulation. This must be done by calling the getNumLoanApplications() function (definition below). After the input of the number of accounts, the program must use loops and random numbers to generate the credit score, score rating, and application result for each loan application in parallel arrays. These arrays must not be declared globally (major error). The following arrays must be declared and populated: creditScores[]...

In C programming: Write a function printAllCourses() which receives an array of course pointers and the array’s size, then prints all courses in the array by calling printCourseRow()

C++ program: Write a function that accepts an array/vector as an input and calculate the sum of all the elements in the array. This function must use recursion to achieve this. Show code: Please show all steps.

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

I am trying to write a rotate function in C language.

Is there any advantage to utilising vectors instead of arrays?

Select all code lines that creates a vector with content {10, 10, 10, 10). You are also given the C-type array, an_array with content (10, 10, 10, 10). std::vector a_vector (an_array, an_array + sizeof(an_array)/sizeof(int)); std::vector a_vector [10, 10, 10, 10); std::vector a_vector (10, 4); std::vector a_vector = {10, 10, 10, 10); Ostd::vector a_vector (4, 10);

Write the following function #input: a numerical vector x #output:the normalized vector, i.e. the vector rescaled into [0,1] # the formula to normalize is (x-min(x))/ (max(x)-min(x)) # you can NOT use the functions min and max # you can use %%, nrow, ncol, and length # you can write multiple functions
