Write a program that prints out the first n primes, and n is input by the user. Example as follows:

How many do you want to see? 3000

1: 2
2: 3
....

25: 97
26: 101
....

2999: 27437
3000: 27449

Program should be written in three files:

primes.h
main.c
is_primes.c

Attached are parts of two files (primes.h, is_primes.c)

Explain how is_prime() works. Complete the program by writting main() in main.c. There are 168 primes that are less than 1000. Does the program confirm this? How many primes are there that are less than 10,000?

Functionality of is_prime function is expressed in following steps.

1. Check whether the argument number (n) is 2. If it is 2 (first prime number) then return 1.

2. Check if n is a multiple of 2. If "n modulus 2" is 0, then n is a multiple of 2 and so it can not be a prime number. Function returns 0 in this ...

Solution Summary

C code in solution assumes fair input to the program and has been tested for compilation with "gcc -Wall -ansi main.c is-prime.c", and for execution with inputs in the set (0-5, 168-170, 1230, 10000).

Hi, I need some assistance with this assignment. It is dealing with pointers. I have attached the assignment and the specs. I have learned how to code and to declare pointers and that is about all I know really. Help would be appreciated, thanks!

PrimeNumbers?
You are to find all the primenumbers between 90,000

A formula that yields primenumbers. One such formula was x^2 - x + 41. Select some numbers for x, substitute them in the formula, and see if primenumbers occur. Try to find a number for x that when substituted in the formula yields a composite number.

I have to write a Java program that meets the following requirements:
Declare a method to determine whether an integer is a prime number
Use the following method declarations:
public static Boolean isPrime (int num)
An integer greater than 1 is a prime number if its only divisor is 1 or itself. For example, isPrime (

Please help with the following problem.
Write a program that computes and prints the 1000th prime number using code blocks c++.
a. You will need some variables to keep track of which prime number you're on and keep track of where you are in your loop.
b. Need to test odd numbers to see if they are prime..
c. Need two l

I have a program i'm having to write for a c++ class. it is dealing with arrays and while loops. we also have to get data from a file, and write it to another. my problem is i can't get it to read the data from the file. here's what the program should be able to do with the data.
1) print out all data in the array with no

What is the probability that 6 numbers drawn in a lottery will be prime? The numbers range from 1-46.
So i know that the firstprimenumbers under 46 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43. Which is a total of 14.
Would it be something like 46!/(14!)(32!)? I don't understand probability that well.

Please respond to the following questions and provide reference if possible. Thank you.
a) What is a prime number, and why are primenumbers important?
b) What do you call a number that is not prime?
c) What is the largest prime number ever found?
d) Is the number 294,822,345,711 prime? How about 173,658,965?

Does a prime number multiplied by a prime number ever result in a prime - Why? Does a nonprime multiplied by a nonprime ever result in a prime - why? Is it possible for an extremely large prime to be expressed as a large integer raised to a very large power? Explain. Are there infinitely many natural numbers that are not pri
