Question

This program that I am confused on is supposed to use a vector of integers to keep up with rolls of a five dice. It should roll the five dice and store the sum of the dice in the vector using the push_back() function. It should then continue rolling the dice until it rolls a 5 of a kind. Insert that final roll into the vector, and then use a loop to compute the sum and average of the elements in the vector. The output should include: the number of rolls it took to get 5 of a kind and the average value of a roll. NOTE: the program should have two functions: (1) a function that sums 5 integers. (Use it to compute the sum of the 5 dice you roll) and (2) a function that returns a bool to determine if the roll is 5 of a kind. Below are function prototypes for the functions:

int sum5(int n1, int n2, int n3, int n4, int n5);
bool fiveOfAKind(int n1, int n2, int n3, int n4, int n5);

Please help THANKS

Explanation / Answer

#include <iostream>

#include <vector>

#include <stdlib.h>

#include <time.h>

using namespace std;

int sum5(int n1, int n2, int n3, int n4, int n5)

{

return n1+n2+n3+n4+n5;

}

bool fiveOfAKind(int n1, int n2, int n3, int n4, int n5)

{

return (n1==n2 && n1==n3 && n1==n4 && n1==n5);

}

int main()

{

srand(time(NULL));

vector<int> diceRoll;

int n1=1,n2=2,n3=3,n4=4,n5=5;

while(!fiveOfAKind(n1,n2,n3,n4,n5))

{

n1 = rand()%6 +1;

n2 = rand()%6 +1;

n3 = rand()%6 +1;

n4 = rand()%6 +1;

n5 = rand()%6 +1;

diceRoll.push_back(sum5(n1,n2,n3,n4,n5));

}

int sumRoll = 0;

float avgRoll;

for(int i=0;i<diceRoll.size();i++)

{

sumRoll += diceRoll[i];

}

avgRoll = sumRoll*1.0/diceRoll.size();

cout<<"Number of rolls : "<<diceRoll.size()<<endl;

cout<<"Average value per roll : "<<avgRoll<<endl;

}
