#include <iostream>
using namespace std;
int main() {
int a=1;
int b;
b = ++a * ++a;
cout<<"a: "<<a<<", b: "<<b; cout<<endl;
a=1; b = a++ * a++;
cout<<"a: "<<a<<", b: "<<b; cout<<endl;
a=1; b = ++a * a++;
cout<<"a: "<<a<<", b: "<<b; cout<<endl;
a=1; b = a++ * ++a;
cout<<"a: "<<a<<", b: "<<b; cout<<endl;
}
OUTPUT:
// a: 3, b: 9
// a: 3, b: 2
// a: 3, b: 6
// a: 3, b: 3
Can anyone explain why, this is the output?
Modifying a variable more than once within the same expression (without sequence points or inter-variable sequencing) results in undefined behavior
