Ok here is the thing

I have some knowledge in php and almost none in c++, because i decided to go with java, so bare with me. Today a friend asked me to do some homework for him, cause he ran out of time and wont be able to do it alone.

I had to create a program that returns numbers that can not be divided with anything but 1 and itself. so if i put in number 10, it returns numbers 2, 3, 5, 7. I hope you understand what i mean.

Ok this was easy and here is the code: (some in slovenian language)

(Toggle Plain Text)

#include <iostream.h>

int main()

{

int d=3;

int c=d;

cout<<"Vpisi stevilo n, do katerega bo po intervalu od 0 do n"<<endl<<"program izpisal prastevila: ";

cin>>c;

if(c%2==0)

c++;

cout<<"1"<<endl<<"2"<<endl;

while (d!=c)

{

bool prastevilo=true;

for(int i=2; i<d ; i++)

if(d%i==0)

{

prastevilo=false;

i=d;

}

if(prastevilo==true)

cout<<d<<endl;

d++;d++;

}

return 0;

}

Now what i need to do is use this in php, which i have no idea how that can be done. But lucky for me i have an example
how all together should look and work.

If anyone has any ideas or an advice plz let me know, and even better if you have the time to make this for me plz help me.

Anything will help so post tutorials, articles, even a simple hint how to do it can get me closer to the solution of this problem.

Thank you and have a nice day

Don't know what those numbers are called in Slovenian, but in English they're called "prime numbers." Here's some code I wrote in another thread:

(Toggle Plain Text)

int prime = 1;

if (number == 1) {
  prime = 0;
  /* 1 is not a prime number */
}
else {
  for (int i = 0; i < sqrt(number); i++)
  {
    if ((number / i == (int)(number / i)) && i != 1 && i != number)
      prime = 0;
      /* i is a factor that is not 1 or the number itself - the number divided by i is the same when converted to an integer. */
  }
}

if (prime == 0) {
  printf("%i is not a prime number.", number);
}
else {
  printf("%i is a prime number.", number);
}

Enjoy.

Hey thnx for the reply, but that is not what i need. I need to know how can i include this .cpp code into my webpage. I really dont know how to do it. (applets in java are so simple

The only way you can execute CPP code from your web is through CGI. Configure your ouput from the C++ prog with CGI/HTML headers... then do all the other "wonderful" things needed... followed by crossing your fingers that your host provides support for CGI scripts on your page.

yeah CGI is a bitch to setup if you don't know what your doing.
