Ask HN: How does “min” and “hour” get their values in this C++ code?

https://imgur.com/a/UCks0vq Full code here: #include<iostream> using namespace std; class Time { public: int hour; int min; Time() { hour=min=0; } Time(int h,int m) { hour=h; min=m; } Time add (Time t) { Time t1; int m=min+t.min; t1.hour=hour+t.hour+m/60; t1.min=m%60; return t1; } }; int main() { Time t1; Time t2(8,40); Time t3(5,30); t1=t2.add(t3); cout<<t1.hour<<" "<<t1.min; return 0; } As shown in the figure above, some of my confusions are clear. But what I fail to understand is how "min" and "hour" gets its value from t2(8,40). I am sorry if this is a too basic question, but I didn't understand so I am asking. If I am missing any prerequisites to this topic, do tell me about them, that'd help me more for self learning.
