Write a function called "extract_prime()" that takes the three vector arrays holding all the random numbers and the boolean variables indicating which are primes as input and produces a new vector of just the prime numbers.

Write a function called "print()" which prints the contents of an array in a formatted fashion as shown below. Specifically, print 8 integers per line in a 3-character wide field with a space separating the numbers. Add code that calls these two functions to output the prime numbers in their order of appearance. Then sort the data and eliminate any multiples of the same number. Output the result.

Consider using "sort()" and "unique()" from STL to do the heavy lifting. Hint: If you implemented "Prime4" using vector arrays, you can use the "erase" member function to get rid of the unwanted data moved to the end by "unique()".

Output as expected:

Prime4 user ./Prime4 Sequence contains 21 prime numbers. All numbers in order appearance: 61 113 13 534117 61 97 59 7 17 137 415 127 31 131 59 109 83 61 Unique values in numerical order: 5 7 13 17 314153 59 61 83 97 109 113 127 131 137 user> user /Prime4 1000 Sequence contains 243 prime numbers.
