Hello all I am having a great degree of difficulty incorpora

Hello all, I am having a great degree of difficulty incorporating two functions into my Assingment for Computer science, a function that splits the entered integer into seperate digits (if possible) and a function that checks to see if the entered number is a prime number or not, and then precedes to list the prime numbers between 1 and the entered integer. Here is my code so far. (Written in Codeblocks)

//{
// int count =0;
// while(n>0)
// {
// count++;
// n=n/10;
// }
// return count;
//}

<< \" You write a sequence of numbers, one after another. Start by writing n.\" << endl
<< \" If n is even, then the next number is n/2. If n is odd, then the next\" << endl
