• For Loop Behavior Different from Tutorial Example

  I am currently learning C++ through the Spoken Tutorial series, and I came across a confusing behavior in the for loop example from the tutorial.In my practice, I am also using Pass4Future CPP Practice Questions to improve my understanding of the concepts. While working on one of these questions, I noticed that my for loop behaves differently than what was shown in the tutorial video.Here is a simplified version of my code:#include <iostream>using namespace std;int main() {    for (int i = 0; i < 5; i++) {        cout << i << " ";    }    return 0;}What I expected: 0 1 2 3 4 but results are differentsI tried to compare it with the tutorial example, but I am still confused about why the behavior is different.Could someone please help me understand why this is happening? Is this difference related to compiler settings, or my code?
