Otherwise, the input is incorrect and the program shows a message and loops back to read a new one.

This is, of course, the job of a DO-loop: Conclusion Determining if a number is prime or printing all prime numbers up to a limit is a common interview question. In most programming languages there is a modulus type function for determining the remainder of a division between two numbers.

Please refer to that example for the details. Check to see if our current index is prime, otherwise ignore it. That one would be quite nice to see here!

The users types in 1 and the same message appears. Since Range is larger than or equal to 2, 2 must be included since it is a prime number. It is asymptotically faster than other methods, but I think it is too slow and cumbersome to be useful on small numbers.

For small enough numbers less than 15 digitsa probabilistic test like Rabin-Miller is sufficient if you take enough bases. There are 25 prime numbers in the range of 2 and Operators are just funny selectors.

In "A and B", "B" will be executed only if "A" evaluates to true. A prime number or a prime is a natural number greater than 1 that has no positive divisors other than 1 and itself. As you already know a functional programming language, I really recommend you learn some sort of Lisp to see it on your own.

October 9th, Program Input and Output The following shows an interaction between the user and program. Write a program to read a value of N, make sure that the value of N is greater than or equal to 2, and display all prime numbers in the range of 2 and N.

In this one, we shall find all prime numbers in the range of 2 and N, where N is an input integer. But are there imperative programming languages with lazy evaluation? Bichromat October 9th, After reading in a correct value for Range, we can start prime number searching.

In case the value of N is less than 2, your program should keep asking the user to try again until a value that is greater than or equal to 2 is read. This is in my opinion a lot more elegant and more efficient. All the other prime numbers are odd numbers.

Loop from two until our new square rooted limit. Create an array from two until the value and assign a value of true since we are going to assume everything is prime to start. This program displays the input value and a message asking the user to try again.

A prime number via Wikipedia is as follows: What is the range? In Lisp you can, as any procedure is a list, so it has a second element! Zugzwang October 9th,Finding All Prime Numbers in the Range of 2 and N Problem Statement.

In a previous example, we have discussed how to determine if a positive integer is a prime killarney10mile.com this one, we shall find all prime numbers in the range of 2 and N, where N is an input integer. Write a program to read a value of N, make sure that the value of N is greater than or equal to 2, and display all prime.

Line 5: Initializing the list of prime numbers in a string.

Line 8: Checking for all the numbers starting from 1 till user's input Line Initializing a flag variable. Write a program that uses that function on each num ber from 1 toand if true, displays that number. Batch file to display prime numbers from ?

I once tried this. Write a script to print all prime numbers from 1 to Adelheid Fischer author of Script to print all prime numbers from 1 to is from Frankfurt, Germany. View All Articles: Related Articles and Code: Program to find entered number is prime number or not; Even number,Prime no.,Factorial of a number; Shell script to print first 5 odd.

Jan 12, · First of all my apologies for literally stealing the idea from this thread which I found very interesting. However a "Hello Ubuntu" program will lack the concept of conditions and iterations, so I wondered it would be great to have a thread which would showcase these concepts in every programming language.

So This is the thread for program which will: (1) Get a number. Java program to find whether given no.
