Using C++ with the following code already written

Task 5

Add a new function, called isPrime(), that takes in a number and returns true if the number is a prime number. Just like with the others, create an output file called primes.txt that contains all of the prime numbers you find.

Determine if a number is prime can be quite time consuming. You will probably want to test your program using the short.txt input file, found here:

Here is the sample output for the full input.txt file. I have also used the unix time command, to show long long it took to run the program over the large input file.

Numbers read in: 100009

Even numbers: 49868

Odd numbers: 50141

Prime numbers: 6774

real 1m12.695s

user 1m12.292s

sys 0m0.376s

Task 6:

Finally, add in the necessary functions to display the maximum, minimum, mean, standard deviation, and sum of these numbers. You have already completed most of these functions in previous assignments.

Expected Output:

Numbers read in: 100009

Even numbers: 49868

Odd numbers: 50141

Prime numbers: 6774

Min number: 27

Max number: 9999930

Sum: 780886019

Mean: 7808.16

Standard Deviation: TBD
