Lab Activity #5-More Functions/FILES Exercise# Write a program that will generate 1000 random numbers (all of which are between 10 and 20) and then write all of the even numbers (from those 1000 numbers) to a new file called "myEvenRandoms.txt Exercise #2 (DO ONLY IF WE COVERED ARRAYS OF CHARACT Write a program that will ask the user to enter a sentence. Then create a separate function that will count the number of vowels in that sentence and display the answer Create your own game! Using the random function for rolling a pair of dice, be creative and create your very own game that uses a single, a pair, or multiple dice. You have free license to design the game and its rules. Have fun!

1.

#include <iostream>

#include <cstdlib>

#include <fstream>

using namespace std;

int main()

{

ofstream wr;

int i,n;

wr.open("myEvenRandoms.txt");

cout<<"Randomly generated even numbers are written to myEvenRandoms.txt file....."<<endl;

wr<<"Randomly generated even numbers :"<<endl;

for(i=1;i<=1000;i++)

{

n=rand()%20+10;

if(n%2==0)

wr<<n<<" ";

}

wr.close();

}

Randomly generated even numbers are written to myEvenRandoms.txt file Process exited after e.05342 seconds with return valuee 6 2 ress any key to continue .. .
