Question

This is C++. I would like to know the TODO list comments.

#include <cstdlib>
#include <iostream>

// TODO: 2. (1 point) Declare your Acker function prototype below:
// When done, commit with the commit message that follows, being
// sure to delete all these TODO instructions before actuallly
// executing the git commit command.
//
// CSC232-HW02 - Added Aker function prototype.
//
// Don't forget to fully document the function prototype using
// all the appropriate doxygen elements.

/**
* @brief Entry point to this application.
* @remark You are encouraged to modify this file as you see fit to gain
* practice in using objects.
*
* @param argc the number of command line arguments
* @param argv an array of the command line arguments
* @return EXIT_SUCCESS upon successful completion
*/
int main(int argc, char **argv) {
    // TODO: 4. (0.5 points) Replace *** text *** with actual call to Acker
    // function. When done, commit with the commit message that follows,
    // being sure to delete all these TODO instructions before actuallly
    // executing the git commit command.
    //
    // CSC232-HW02 - Display calculated Acker value.
    //
    std::cout << "Acker(1, 2) = " << "*** replace me with call to Acker***"
             << std::endl;
    return EXIT_SUCCESS;
}

// TODO: 3. (2 points) Define the Acker recursive function below. When done,
// commit with the commit message that follows, being sure to delete
// all these TODO instructions before actually executing the git
// commit command.
//
// CSC232-HW02 - Implemented Acker function.

// TODO: 5. (1 point) Do a box trace of Acker(1, 2) using pen and paper.
// Hand this in at the beginning of class on Friday, 17 February 2017.
// Your solution MUST be legible; no points are assigned to illegible
// papers.

This is testRunner.
