Here, x = 20; & y = 35; given, x= y++ + x++; so in this case, first we put the value of variables, x = 35+ 20 = 55 but here, x is increament so,we have to find the value of x, therefore, x++= 20+1=21, so, x = 35+21 = 56 . so the answer is 56.its correct..

If it did, the stack would be more complicated, function calls would be more expensive, and programs would run a lot slower. If you...
