Question

Write a program to find out twin prime numbers between 10 and 1000. Twin prime numbers are defined as two consecutive odd numbers, which are prime.

Answer 1

Answer:

Given an integer n. we need to print all twin prime number pairs between 1 to n. A Twin prime are those numbers which are prime and having a difference of two ( 2 ) between the two prime numbers. In other words, a twin prime is a prime that has a prime gap of two.

Sometimes the term twin prime is used for a pair of twin primes; an alternative name for this is prime twin or prime pair. Usually, the pair (2, 3) is not considered to be a pair of twin primes. Since 2 is the only even prime, this pair is the only pair of prime numbers that differ by one; thus twin primes are as closely spaced as possible for any other two primes.
