    C uses the short-cut evaluation method.

    For efficiency, it is a good programming style to use side effects in binary expressions.

    In the short-cut evaluation method, it is possible to determine the result by evaluating only the first operand.

Explanation / Answer

Solution:

For efficiency, it is a good programming style to use side effects in binary expressions.

This statement is false. side effects can lead to logic problems, and good programming style recommends to avoid side effects.
