How do you print prime numbers in an array?

Logic:

  1. We are declaring an array (arr) with the elements: 100, 200, 31, 13, 97, 10, 20, 11.
  2. To check prime numbers, we declare a function isPrime() that will return 1, if number is prime and return 0 if number is not prime.

How do you get 100 prime numbers?

Algorithm to generate 100 prime numbers

  1. We first define a variable num and initialize it to 1 and a variable count=0 and put it in a loop till it reaches 100.
  2. Then we initialize 2 variables flag to 0 and i to 1.
  3. We then check if num is divisible by i, which takes up value till it reaches num.

What is the trick to find prime numbers?

To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can’t be a prime number. If you don’t get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).

Is it possible to sort the elements of an array?

It is not possible to obtain sorted array.

How do you write pseudocode for prime numbers?

Pseudocode

  1. INPUT n.
  2. i = 2.
  3. answer = prime.
  4. WHILE i <= n / 2.
  5. rem = n \% i.
  6. IF rem is not equal to 0.
  7. i = i + 1.
  8. ELSE.

What is the biggest prime number between 89 and 100?

Prime numbers list. List of prime numbers up to 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

How to counter more than one number in an array?

Instead of this, try to do the following int counter = 0; int num = number; while(counter < 10){ num++; if(num\%2 == 0){ array[counter] = num; counter++; } } Use a while loop which will consider the amount of numbers greater than your input that are even (num\%2==0) and assign to your array in the position of the current counter
