Can someone explain this. How it works .

Question

int main()
{
int x=3;
while(x++<10){
x+=2;
}

cout<<x; //Output 13
}

Answer 1

3
3<10 true // first check then increment
3++ => 4
4+2 => 6
6<10 True
6++ => 7
7+2 => 9
9<10 True
9++ => 10
10+2 => 12
12 < 10 False
12++ => 13
hence x is 13

Ani Jona 🕊 thanks for the correction

Answer 3

In the while loop, you are adding 3 on each loop, the x++<10 means that x will be checked and get incremented by 1. When x = 9, it will be true, then x will become 10, then add 2 (x=12). In the last loop, x get incremented by 1(x=13), but the loop stops.

ah so... Thanks

Answer 5
