What will be the output and how it will be?

Question

#include <iostream>
using namespace std;

int main() {
int x,y,z;
x=10;
y=15;
z=x+++y;
cout<<x<<endl;
cout<<y<<endl;
cout<<z;
return 0;
}

Answer 1

#include <iostream>
using namespace std;

int main() {
int x,y,z;
x=10;
y=15;
z=x+++y; // x = 11, y = 15, z = 11 + 15 = 25
cout<<x<<endl; // 11
cout<<y<<endl; // 15
cout<<z; // 25
return 0;
}

Output:
11
15
25

Answer 2

Copy paste it in a compiler and you will know.
Even SoloLearn has one

Answer 3

z=x+y.. then add 1 to x
so x=11, y=15, z=10+15=25
