Question

Vulpes · Answer

I haven't used Turbo C for many years but the result of this expression is just the same in the Visual C compiler. Basically the operands are determined before the result of the multiplication operator is calculated. Consequently 'a' gets incremented twice on both sides of the * operator.

Hey 81 is right the expression executed as follows. 1. As a=7 it solve first bracket and increment the value of a to 8. 2. In second step the second bracket is solved and again it increment value of a to 9. 3. Then multiplication operation takes place as 9*9=81. 4. And then 9 is assigned to b.
