Set-up and implementation code for a void function MaxYou are not required to write a complete C++ program but must write and submit just your responses to the four specific function related questions below: QC1: Write the heading for a void function called Max that has three intparameters: num1, num2 and greatest. The first two parameters receive data from the caller, and greatest is used to return a value as a reference parameter. Document the data flow of the parameters with appropriate comments*. QC2: Write the function prototype for the function in QC1. QC3: Write the function definition of the function in QC1 so that it returns the greatest of the two input parameters via greatest, a reference parameter. QC4: Add comments to the function definition* you wrote in QC3 that also states its precondition and postcondition.
Complex numbers Program a new data type for complex numbers. (In C/C++ this can be done using a struct or by defining a new class.) Write functions or operators for addition, subtraction, multiplication, division and absolute value. Test each operation at least once in a main()-program.
6: Write a program in C++ that contains overloaded functions with name óvoperation(). When the main program makes a call to Ovoperation the program performs the following according to the arguments of the function call: • Ovoperation(): returns an int 0. • Ovoperation(float, float) returns the maximum between the arguments. • Ovoperation(int, int, int) returns the minimum value among the arguments. • Ovoperation{char) return the next ASCII character (e.g. OpOperation('a') returns b').

C++ PE04 - Functions and Prototypes For this exercise, you'll complete two problems. Problem 1 - Function Declarations Write the prototypes for several function calls, deducing the correct signature from the context in PrototypeTester.cpp Do not implement the functions themselves. That is already done. Place the prototypes in pe04.h. Problem 2 - Write a Function Write a function named binToDec() that accepts an integer parameter whose digits are meant to represent binary (base-2) digits, and converts that integer's representation to decimal (base-10). The function should return the integer value before it was converted. For example, given this code: int a = 101011; int b = binToDec(a); cout << "a->" << a << ", b->" << b << endl; The output is: a->43, b->101011 Constraints: Do not use a string in your solution. Also do not use any built-in base conversion functions from the system libraries. You must program this by "hand". pe04.cpp 1 2 3…
Question 1 Answer the following question Write a code in c++ to declare a structure Bird having the following members Name Color ID write the following functions for the structure Bird. a) Write a function to take input from the user for five birds. The information must be visible in the main. Write a function that finds the Birds having palindromic id and prints their information in main. Write a function that asks the user to enter the bird id and remove the information of the Bird having that id.

That is already done. Place the prototypes in pe04.h. Problem 2 - Write a Function Write a function named quadratic() which computes roots of quadratic equations. Recall that a quadratic equation is one of the form, ax2 + bx + c = 0. Your function accepts five arguments: The integer coefficients a, b, and c as three input parameters. Two real number (double) output parameters root1 and root2. Your function should compute the two roots of the quadratic equation and store them into the two output parameters. For example, the equation x2 - 3x - 4 = 0 has roots of x = 4 and x = -1, so the call: double root1, root2; quadratic(1, -3, -4, root1, root2); should set root1 to 4.0 and root2 to -1.0. You may assume…
