Explain the logic...🙏

Question

#include <iostream>
using namespace std;

int main() {
int i=1;
if(i++ && (i==1))
cout << i << " YES" << endl;
else
cout << i << " NO" << endl;
return 0;
}

Can anyone give me the answer. Why this code give output "2 NO" ...

How is it possible when we know that the priority of == is greater than ++?

Answer 1

priority only apply inside a single expression, while the 'if' test for 2 expressions (concatenated by logic &&):
first i is evaluated to 1, then i is incremented (i==2), then as 1 is true, the second expression i==1 is evaluated to false, as now i==2!=1...
