#include<stdio.h>
#include<math.h>
void main()
{
int n,i,prime=1;
printf("input the numbers");
scanf("%d",&n);
for(i=2;i<=sqrt(n);i++)
if(n%i==0)
{
prime=0;
break;
}
if(prime)
printf("%d is a prime number",n);
else
printf("%d is a not a prime number",n);
}

find the output? void r(int a[],int c, int n) { if(c>n) { a[c]=a[c]+c; r(a,++c,n); r(a,++c,n); } } int main() { int i,a[5]={0}; r(a,0,5); for(i=0;i<5;i++) printf("\n %d",a[i]); getch(); }
