Web7 mei 2011 · A prime integer number is one that has exactly two different divisors, namely 1 and the number itself. Write, run, and test a C++ program that finds and prints all the prime numbers less than 100. (Hint: 1 is a prime number. For each number from 2 to 100, find Remainder = Number % n, where n ranges from 2 to sqrt (number). Web(We can say this with certainty because the largest gap between any primes up to 18 digits is only 1442; this gap happens between the primes 804212830686677669 and 804212830686679111. The interval (n 2, (n+1) 2) is wider than 1442 when n > 720, so Legendre's conjecture seems a safe bet, up to 18-digit primes.) Back to statement (B).

So, the distance between any two prime numbers in a row (called successive prime numbers) is at least 2. In our list, we find successive prime numbers whose difference is exactly 2 (such as the pairs 3,5 and 17,19). readypower group logo
