In C++, can I get a code example for a function that will return the intersection items for two sets. It will return/print out the shared (intersection) items for them. I am looking for an actual function preferably for a set class, comparing one instance of a set class with another, but definitely NOT a STL keyword. Thank you.

DateType keeps only the integer representation of the month,day, and year. When a month is wanted in string form, the string iscalculated. An alternate approach would be to add a string field tothe date and calculate and store the string representation in theInitialize function. Which methods would have to bechanged? Would this change make the use of an if statement tofind the appropriate string more or less attractive? Write the code in C++for this if statement.

Write a C++ Program using classes, functions (recursive and otherwise), arrays and other C++ commands to sort a file using Selection Sort.  The user will enter the filename.  The file should be sorted by the following fields:  first by Last Name, then by Mother’s Maiden Name, then by First Name and finally by Second Name (or Initial).  The sorted file should be written to file and the first 10 results displayed on screen.   Use the following format for both the screen output and the file created: ----------------------------------------------------------------| Last Name | Mother’s Maiden Name | First Name | Second Name  | ----------------------------------------------------------------|  Saotome  | Tendo                | Ranma      | P            | |---------------------------------------------------------------|  Son      | Kakarot              | Goku       | A            |----------------------------------------------------------------|  Yeager   | Kaiser               | Eren…

In C++, what is the difference between emplace_back and push_back, when using vectors? I looked at other sources, and still find it confusing as to what s the difference between the two of these.

I need help with this assignment, I need to make a struct to implement a limited Python style list in C++. When you bootstrap the exercise, you will be given a main.cpp file, with a simple program written in it. The program declares a Python style list and appends several elements to it, before printing it out to the terminal. The file is where I would setup my code #ifndef PY_LIST_H #define PY_LIST_H   #include <iostream>   struct PyList { // Declare your vars here   PyList(){ // Implement this }   void append(int x){ // Implement this }   void append(char x){ // Implement this }   void append(float x){ // Implement this } ~PyList(){ // Implement this }   };   std::ostream& operator<<(std::ostream& os, const PyList& pyList){ os << '[';   // Complete this implementation   os << ']'; return os; }   #endif   Here is the main.cpp file that it must be able to run and the float must not have floating zeros #include <iostream> #include "PyList.h"…

Implement the following functions. Each function deals with null terminated C-Style strings. You can assume that any char array passed into the functions will contain null terminated data. Place all of the functions in a single file and then (in the same file) create a main() function that tests the functions thoroughly. You will lose points if you don't show enough examples to convince me that your function works in all cases. Please note the following: You may not use any variables of type string. This means that you should not #include <string>. Also, you may not use any c-string functions other than strlen(). If you use any other c-string functions, you will not get credit. Note, however, that functions such as toupper(), tolower(), isalpha(), isspace(), and swap() are NOT c-string functions, so you can use them. Also note that this prohibition is only for the functions that you are assigned to write. You can use whatever you want in your main() function that tests the…
