Question

here is the codes to a game in C++ but i need to modify it so it will work right, all the sections that have comments are the section that needs to be modified. whoever gets to number 50 first wins the game, you can only add max number 6 to original guessed number but you can add 1 to 6.

// standardaddgame.cpp : Defines the entry point for the console application.

//

#include <iostream>

#include <limits>

#include <string>

#include <cmath>

#include <stdio.h>

#include <stdlib.h>

#include <time.h>

int readNumber(int number, int max_number, int max_increase);

try this code buddy this will be helpfull...
