-sharpinclude <iostream>
using namespace std;
int main()
{
int x = 0;
int y = 0;
int input = 0;
cout << "Input a number:" << endl;
cin >> input;
input ? PPy, PPx : --x, --y;
cout << "x = " << x << endl;
cout << "y = " << y << endl;
return 0;
} PPy, PPx and PPx, PPy are the same, with , , not ; , belonging to the same sentence, no problem.
the comma operator has the lowest precedence, so the two ways are equivalent to
(input? PPx, PPy:-- x),-- y and (input? PPy, PPx:-- x),-- y
so, of course, the result is the same.
(input ? PPy, PPx : --x), --y;this-- y is bound to be carried out. Do you understand?
