WebbThat is, given any composite number there is one and only one way to write it as a product of primes, as long as we are not particular about the order in which the primes occur. So, for example, we regard 2 × 3 × 5 × 7 as the same as 3 × 5 × 7 × 2, or any other possible order in which these primes are written.

Create a function called bool isPrime (int value) that returns true or false depending on whether value is prime. Then test it with various values. Right now, you have everything all munged in the main function, making the issue more difficult to debug. With a function, you can test it with various values first.
Steps to implement this approach: Make two vector prime and nonPrime to store prime and non-prime numbers. After that traverse the whole input array and if any number is prime then push that into the prime vector else into the nonPrime vector.
