explain output

Question

can somebody explain why this outputs as 12?:
int f=1, i=2;
while(++i<5) {
f*=i;
}
cout<<f;
thanks!

Answer 1

Yes, you're right ;)

Answer 2

ah i think i understand now, but please feel free to correct me if this reasoning is wrong
i increments to 3
3*1 = 3
i increments to 4
3*4 = 12
and then it terminates bc i would no longer be <5
