class Demo{
static boolean prime(int n){
int c=0;
for(int i=0;i<n;i++){
if(n%i==0){
c++;
}
}
if(c==2){
return true;
}else{
return false;
}

public static void main(String[] args){
int[] arr={2,5,7,6,8,11,14,13,50};
for(int i=0;i<arr.length;i++){
if(prime(arr[i]){
System.out.println(arr[i]+" ");
}
}
}

Is the following code legal? void main() { typedef struct a aType; aType someVariable; struct a { int x; aType *b; }; }
