Did it on my own yeah haha thanks everyone for the help

Ok it works now the only bit i need help with now is the distinct positve factors part any ideas?

It wont happen

Ok the program i posted works the only thing is that when the number is prime it does not say the number is prime so that print must be in the wrong place so is it a problum with my brackets?

#include<stdio.h>
#include<math.h>
int main(void){
int n,i,a;
printf("enter the number");
scanf("%d",&n);
for(i=2;i<n;i++)
{
...

#include<stdio.h>
#include<math.h>
int main(void){
int n,i,a;
printf("enter the number");
scanf("%d",&n);
for(i=2;i<n;i++)
{
a=n%i;
if(a==0)

should it be a while loop

for(i=2;i<=n;i++)
is it to do with this line

Crap do u no what is wrong wit the code?
