- The object can't be (i) Passed by reference (ii) Passed by value (iii) Passed by copy (iv) Passed as functionInstructions: In the code editor, you are provided with a treasureChestMagic() function which has the following description: Return type - void Name - treasureChestMagic Parameters - an address of an integer Description - updates the value of a certain integer randomly You do not have to worry about how the treasureChestMagic() function works. All you have to do is ask the user for an integer and then call the treasureChestMagic() function, passing the address of that integer you just asked. Finally, print the updated value of the integer inputted by the user. Please create a main code for my function that works with this. This is my code: #include<stdio.h>#include<math.h> void treasureChestMagic(int*); int main(void) { // TODO: Write your code here return 0;} void treasureChestMagic(int *n) { int temp = *n; int temp2 = temp; *n = *n + 5 - 5 * 5 / 5; temp2 = (int) pow(2, 3); if(temp % 3 == 0) { *n = temp * 10; } else if(temp %…Reference variables can be polymorphic.

- C++HurdleGame The HurdleGame class contains all the functions invoked as a result of a user action (i.e. when a user presses a key on the Hurdle Frontend, one of the functions in HurdleGame will be called. A HurdleGame object comprises a HurdleWords object (which stores all valid guesses and valid Hurdles), and a HurdleState object, which stores and tracks all the game states. Any action should update the HurdleState object.Each function in HurdleGame is called as a result of a user action on the Hurdle Frontend. To understand this, please read the Hurdle Backend API section below before implementing. You are responsible for implementing each of the functions below. LetterEntered ● Called by the Hurdle frontend when the user enters a letter. ● Hint: when a user enters a letter, how should the underlying HurdleState be modified to reflect the change resulting from that key press?

Acomplex number is a number of the forma+b*i,where, for our purposes, a and b are integers and i represents sqrt(-1).In your class, include a constructor that takes two parameters andinitializes a and b to the first and second parameter respectively, and includea constructor that takes one parameter and initializes a to the value of theparameter and b to 0. Also include a default constructor that initializes both aand b to 0. Overload all of the followind operators so that they correctly applyto the class Complex: ==, +, -, *, >>, and <<.Using your Complex class, write a program that would let the user input twocomplex numbers, and then print out their sum, difference, product, and whetherthey are equal to one another.3. Set the username for the newly created object to "user+userld"(user10001).
