Why iostream is in double quotes? Why if we run same code in dev c compiler gives correct output as 3 ; why not here?

#1

#include “iostream”
using namespace std;
int main(int argc, char* argv[])
{
int x,y;
cin>>x>>y;
int num = x^y;
cout<<num ;

return 0;

}

@dhruvtrehan45hey iostream will be in bracket only and this programme will return the xor of two input numbers.
