WebThe sieve of Eratosthenes, named after Eratosthenes of Cyrene, is a simple algorithm dating from Greek antiquity giving all the prime numbers up to a specified integer in a rectangular array, by identifying the primes one by one and crossing off their multiples.Often it is presented as a 10 × 10 array showing the 25 primes up to 100.. It is especially convenient … WebComputer Science. Computer Science questions and answers. Problem 2: Prime numbers Write a program that generates all prime numbers between 2 and 1000, using the Sieve of Eratosthenes method. You can find many articles that descrībe the method for finding primes in this manner on the Internet. Display all the prime values.

(well 49 actually). The numbers 50-100 don't even need to be checked for one of two reasons: a) they will already be correctly marked as prime by checking the numbers from 2-49 or b) Why do you need to check multiples of the number 75 if you stop at 100? truflight 2 golf simulator
