You can write out this algorithm. This will then be programmed into the device to make determining prime numbers easier.
Find a prime number, add 2 to the number. Check if the new number is prime. IE : 3 is prime. 3+2 =5. 5 is prime. (3,5) are twin primes.
VBnet program to find the prime numbers between 100 to 200?
Write a function that implements an algorithm that checks to see if a particular integer is prime (returning a boolean). Write a program that uses that function on each number from 1 to 100, and if true, displays that number.

First write a program to generate the prime number. After one prime number was generated, divide the big int number by the prime number. If the remainder is zero then quotient is the second prime number ( also it is important to check whether the quotient is prime number or not because sometimes you will get wrong answer). Repeat the process until you get the result.

Write your own prime number program and find out.
Write a function that implements an algorithm that checks to see if a particular integer is prime (returning a boolean). Write a program that uses that function on each number from 1 to 100, and if true, displays that number.
You can check each individual number, whether it is a prime number. For numbers below 100, it is enough to check whether they are divisible by 2, by 3, by 5, and by 7. If a number is divisible by none of these, it is a prime number.

29 is a prime number, meaning it has no smaller factors. For any number up to 120, to check whether it is prime or not, it is sufficient to check whether it is divisible by the first four prime numbers (2, 3, 5 and 7).
Since there is an infinite set of prime numbers the answer would be infinity.
