I can't understand why I get compile error!
I don't see nothing strange in my code and it works perfectly in my computer, so I don't know what to change
here is my code:

#include <stdio.h>
#include <math.h>

int p[15003],ind=5;

is_prime(int n){
int i=3,l=sqrt(n)+1;
while(i<l){
if(n%i==0)
return 0;
i+=2;
}
return 1;
}

init(){
int i;
for(i=11;ind<15002;i+=2){
if(is_prime(i)){
p[ind]=i;
ind++;
}
}
}

int main()
{
p[1]=2;p[2]=3;p[3]=5;p[4]=7;
int n,i,k;
init();
scanf("%d",&n);
for(i=1;i<=n;i++){
scanf("%d",&k);
printf("%d\n",p[k]);
}
return 0;
}

is someone can help me I would appreciate....
thanks!
bye

Put SQRTL instead of SQRT and you'll get AC...

thanks for your reply
but I try it by changing "sqrt" for "sqrtl" and it doesn't work
maybe it is something else
thanks anyway!
byee

I submitted your source with C++ and sqrtl and got AC...

yes you are right
I submit it but in C so I get compilation error
thanks :D !!!!!

(int)sqrt((double)n)-it is a true

while (i*i<=n) - it's true
or
i = 0;
while (p[i]*p[i]<=n)...
