print all prime numbers up to 100

There are infinitely many prime numbers.

A prime number is defined as a natural number greater than 1 that has no other factors than 1 and itself

A natural number greater than 1 that is not divisible by other natural numbers except 1 and itself is called a prime number ; otherwise, it is called a composite number.
