Question

In this case we will do automated testing against your program. In order to do this you will prompt (ask for input) for a random seed and use it to seed your random number generator. This will allow you to test your program against several seeds. And we will test your program with a series of these random seeds. And this will not be your entire grade, but your ability to pass these tests is a part of your grade. This is a common industry practice and one we will try to introduce you.

Answer 1

C++ code is given below with appropriate comments

Step-by-step explanation:

#include<iostream>

#include<cstdlib>

using namespace std;

// takes in the horses int array and its size

// for each horse perform a toss

void toss(int horses[],int horse_count){

for(int i=0; i<horse_count;i++){

// if the toss result is 1 we advance the horse

// if the result is zero we dont advance

bool advance= rand()%2==1;

if(advance)horses[i]++;

}

}

//takes in the horses int array and its size

// returns true if there is a winner

// else returns false

bool isWinner(int horses[], int horse_count){

for(int i=0; i<horse_count;i++){

if(horses[i]>=15){

cout<<"Horse "<<i<<" wins!"<<endl;

return true;

}

}

return false;

}

// takes in the horses int array and its size

// prints the horses with the track

int print(int horses[], int horse_count){

for(int i=0;i<horse_count;i++){

for(int track=1; track<horses[i];track++)cout<<".";

cout<<i;

for(int track=horses[i]+1;track<=15;track++)cout<<".";

cout<<endl;

}

cout<<endl;

cout<<endl;

}

int main(){

unsigned int seed;

cout<<"Please enter a random seed: ";cin>>seed;

srand(seed);

const int HORSES_COUNT=5;

// we have taken an int array

// the numbers are all set to 1

// if the toss turns 1 we increment the value for that horse by 1

// we keep on incrementing until the number is 15

int horses[HORSES_COUNT]{1};

// repeat the loop until there is a winner

while(!isWinner(horses,HORSES_COUNT)){

toss(horses,HORSES_COUNT);

print(horses,HORSES_COUNT);

}

}
