Use the isprime function that you wrote in programming challenge 21 in a program that reads in an integer that is less than 3001 stores a list of all the prime numbers from 2 through that number in a file name d "primelist. txt". prompts and output labels. no prompts, no labels. after closing the file, the program writes "prime numbers written to primelist. txt." on a line by itself in standard output . input validation if the value read in exceeds 3000, the program silently terminates. // function prototype bool isprime(int);
