4) Lab Exercise For this lab you must extend and revise the program that you created for lab 8. You must: 1. 2. 3. 4. Ask the user how many cars they would like to race Get the name of each driver from the user Store all the cars in a vector Simulate the race for all the cars. In all other respects this program should work just like the program you were asked to create for Lab 8

Explanation / Answer

#include <iostream>
#include <stdlib.h>
#include <time.h>
#include <vector>
using namespace std;

// include Car header file
// so we can declare and use Car objects
// NOTE: the use of quotation marks instead of angle brackets
// for user created header files
#include "Car.h"

int main()
{
   int n;
   cout<<"Enter the number of cars you would like to race: ";
   cin>>n;
   vector<Car> arr;
   // 1. The user will be asked to provide the names for the drivers of the all the cars
   for(int i=0;i<n;i++)
   {
    string driverName;
    cout<<"Enter the name of driver"<<i+1<<" :";
    cin>>driverName;
    Car temp(driverName);
    arr.push_back(temp);
   }
   int minutes = 0;
   srand(time(0));

   // 2. Set each car
