When an object of q2 is created , the value stored in it's d = 36.0
In the next statement , the scope of variable d declared is in only in the main .
When calculate(16) is called then the value 16 is passed is (i) in the function named calculate.
Since this value of i which is 16, is greater than 0 , therefore else statement will be executed resulting in d = i * d = 16*36 = 576.0 and the next statement will print d(calculate) == 576.0
Thus calculate(16) returns 576.0 and there is typecasting of int therefore resA variable will store 576
Hope this solves your doubt , please give an upvote if it does .
THANK YOU.
