C++ 1. Create a vector of 100 randomly generated integers. Use the count_if function and a lambda function to count the number of even numbers in the vector. 2. Repeat Problem 1 for odd numbers.

In C++, define an integer vector and ask the user to give you values for the vector. Because you used a vector, so you don't need to know the size. user should be able to enter a number until he wants(you can use while loop for termination. for example if the user enters any negative number, but until he enters a positive number, your program should read and push it inside of the vector). the calculate the average of all numbers he entered.

Answer in C++ code please! (Duplicate Elimination with vector) Use a vector to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the vector only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Begin with an empty vector and use its push_back function to add each unique value to the vector.

need help in C++ Problem: You are asked to create a program for storing the catalog of movies at a DVD store using functions, files, and user-defined structures. The program should let the user read the movie through the file, add, remove, and output movies to the file. For this assignment, you must store the information about the movies in the catalog using a single vector. The vector's data type is a user-defined structure that you must define on functions.h following these rules: Identifier for the user-define structure: movie. Member variables of the structure "movie": name (string), year (int), and genre (string). Note: you must use the identifiers presented before when defining the user-defined structure. Your solution will NOT pass the unit test cases if you do not follow the instructions presented above. The main function is provided (you need to modify the code of the main function to call the user-defined functions described below). The following user-defined functions are…

8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.

C++ Create a function append(v1, v2) that adds a copy of all the elements of vector v1 to the end of vector v2. The arguments are vectors of integers. Write a test driver.
