#include<iostream> using namespace std; int pri(int a) {int i; for(i=2;i<a;i++) if(a%i==0) return 0; else return 1;} int main(){

Answer 1

Your code showing incomplete i think u made program for prime numbers right . Your main function is missing

#include<iostream>
using namespace std;

int prime(int a)
{
for(int i=2;i<a;i++)
{
if(a%i==0)
return 0;
else
return 1;
}
}

int main(){

cout<<prime(7);
return 0;

}
