Question

True or False? In C++, the expression (a + b / c) / 2 is implicitly parenthesized as ((a + b) / c) / 2.

Answer 1

Answer:

False

Explanation:

The two statements are NOT equivalent since the first statement follows the rule of operator precedence in C++ which assigns highest precendence to values in parenthesis, then division, multiplication, additions and subtraction in that order. In other verify their difference consider this code snippet

      int a =2;

       int b =3;

       int c =5;

       cout( (a + b / c) / 2); // outputs 1

       cout(((a + b) / c) / 2); // outputs 0 because a+b is evaluated first
