Hello all i am so new and trying to learn while i serve.
I am supposed to write a program that prints out the first n primes, where n is input by the user. I am supposed to write my program in its own directory in three files: primes.h, main.c, and is_prime.c
This is what the output is supposed to look like:

PRIMES WILL BE PRINTED.

How many do you want to see? 3000

    1:      2
    2:      3
    3:      5
    4:      7
    5:     11
   .....
   25:     97
   26:    101
 .......
 2998:  27431
 2999:  27437
 3000:  27449
 ........
10000:

This is the files that I have so far:
is_primes.h:

#include <stdio.h>
#include <stdlib.h>

int   is_prime(int n);

is_prime.c

#include "primes.h"

int is_prime(int n)
{
   int   k, limit;

   if (n == 2)
      return 1;
   if (n % 2 == 0)
      return 0;
   limit = n / 2;
   for (k = 3; k <= limit; k += 2)
      if (n % k == 0)
         return 0;
   return 1;
}

main.c

#include "primes.h"

int main(void)
{
   printf("PRIMES WILL BE PRINTED\n\n");
   printf("How many do you want to see?     \n");
   scanf("%5d", 
   return 0;
}

I dont know how to link it to the files and what to fill in the main.c file to make it work. Some guidance would be great

Please use the Code Block when you have code in the posts
Give an appropriate Title. Your title said Visual Basic and you gave the code of C/C++. I edited it for you.
You just happen to post in Introduce yourself and I moved to C-C++ for better response.
Also you had the same post as an article of C-C++

It depends on your compiler. Read your compiler instructions, then if you don't understand them, post back, naming your system and compiler.

You need to compile them together or what?

if yes, one way is to copy "is_primes.h" and "is_prime.c" in libraly of Builder or visual studio(if you have)
to "include" - you ll find it , where your program(builder/studio) is installed. if you cant (so you have linux and "vim"), then you collect ALL this programs in compiling directory and write, as usual , "gcc..."
