Explain why the following code does not conform to the C++ standard. #include int main() { int length; std::cin >> length; double data[length]; return 0; } Your answer may include a compiler error, but that alone is not a sufficient answer. Your explanation should consist of a few sentences, and must use the vocabulary we have de- veloped during the course regarding memory allocation.

C++ Data structures and Algorithms Question: Explain why recursion is important? Write down the pseudocode and execution of a recursive algorithm. The algorithm must be recursively called for 20 times?

1] Write a simple C/C++ program that shows that C/C++ does not check the index range for static one-dimensional arrays, and briefly explain how the program is supposed to check it. 2] Write a simple program in Python to detect whether the scoping of variables is static or dynamic, and briefly explain how the program is supposed to check it.

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…
