I am currently coding in C++, using Dev C++ application. I keep getting the error " 'null' was not declared in this scope." The line of code that it is refrencing is " std::srand(std::time(null));". I have no idea what is happening or how to fix it.

please code this for me in c++ using void, functions, loops, (basic c++ not complicated or highlevel please). I tried to code it myself but there are many mistakes I dont know how to fix so please write a similar one for me but it works.  The question is only 1 but it has 2 parts (2 different functions that should be in one code)       MY CODE:  #include <iostream>using namespace std; int IsPalindrome(int p);void GCD(); int main (){    int choice;    cout << "Please enter a choice: "<<endl;     cout << "Enter one for IsPalindrome "<<endl;    cout << "Enter 2 for GCD "<<endl;    cout << "Enter 3 to exit the program "<<endl;     cout << "Choice: "<<endl;     cin >> choice;            if (choice == 1)    {        int p;        cout << "Please enter a 3 digit number: "<<endl;         cin >> p; if(p%10==p/100)      {  cout<<p<<" is a palindrome " <<endl;  }  else {…

In this lab, you use what you have learned about parallel arrays to complete a partially completed C++ program. The program should: Either print the name and price for a coffee add-in from the Jumpin’ Jive Coffee Shop Or it should print the message Sorry, we do not carry that. Read the problem description carefully before you begin. The file provided for this lab includes the necessary variable declarations and input statements. You need to write the part of the program that searches for the name of the coffee add-in(s) and either prints the name and price of the add-in or prints the error message if the add-in is not found. Comments in the code tell you where to write your statements. Instructions Study the prewritten code to make sure you understand it. Write the code that searches the array for the name of the add-in ordered by the customer. Write the code that prints the name and price of the add-in or the error message, and then write the code that prints the cost of the total…

Must be in C# and this assignment only Rare Collection. We can make arrays of custom objects just like we’vedone with ints and strings. While it’s possible to make both 1D and 2D arrays of objects(and more), for this assignment we’ll start you out with just one dimensional arrays.Your parents have asked you to develop a program to help them organize the collectionof rare CDs they currently have sitting in their car’s glove box. To do this, you will firstcreate an AudioCD class. It should have the following private attributes. String cdTitle String[4] artists int releaseYear String genre float conditionYour class should also have the following methods: Default Constructor: Initializes the five attributes to the following default values:◦ cdTitle = “”◦ artists = {“”, “”, “”, “”}◦ releaseYear = 1980◦ genre = “”◦ condition = 0.0 Overloaded Constructor: Initializes the five attributes based on values passedinto the formal parameters◦ If condition is less than 0.0 or greater than 5.0,…

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.

Can you please help me write the code in C++? It needs to be exactly wrote like the example in black. Also, if you can include a random number generator between [1,9] for the Matrixes then, that would be great. Note: Use DO-WHILE loop to verify user input for scale factor.

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"…

This assignment will give you practice on basic C programming. You will implement a few Cprograms

List two features we used from the C++ standard library, including a short explanation of why you would use the feature and which header file must be included. Example: The std::cin object is found in the iostream header file and is used to read characters from the keyboard.
