————————————————————————————————————————

the instructions were:

Create a Micro casino that will either flip a coin, roll dice for snake-eyes, or do a permutation of number of aces.

tossCoin , will take a positive integer and flip the coin, count the number of heads and return the number of heads.

rollDice, will take a positive number, roll two dice (values from 2 to 12) and return the number of snake-eyes (value of 2).

factorial, take a positive number and return its factorial (there are several examples of factorial).

acesHand, given that you have 7 aces in your hand, how many ways can you select X number of aces from that hand (permutations, pass the X number to the function and X has to be in range of 1 to 7).

You need the random number generator for the tossCoin and rollDice.

For C++, include:

#include <iostream>

#include <stdlib.h>

#include <time.h>

Then in main as one of the first statements, set the seed like:

srand(time(NULL));

Note: you do the srand ONLY once! Then use the rand() to get the random number (can rand multiple times).

For Java, do:

import java.util.Random;

And in main, do:

Random randNums = newRandom();

Then to get a random number you do:

int rand = randomNums.nextInt(n);

Where n is an integer value to go from 0 to <n (like randomNums(6) give 0 to 5, NOT 6).

A sample run would look like:

**Micro casino**

**1) flip a coin**

**2) roll dice for snake-eyes**

**3) permutation of number of aces**

**0) quit:** 2

**Number of snake-eyes 7 out of 101 throws**

**Micro casino**

**1) flip a coin**

**2) roll dice for snake-eyes**

**3) permutation of number of aces**

**0) quit:**

Note: use a prime number (constant) as the number of tosses to pass to either flip a coin or roll dice for snake eyes.
