The following expression, for example, evaluates to 1
only if the
value of the ratio
variable is between 10 and 30:
10 < ratio && ratio < 30
Accordingly, the printf
statement embedded in the following
if
statement is evaluated only if the value of the ratio
variable is in the 10-to-30 range.
if (10 < ratio && ratio < 30) printf ("It is in the normal range.\n");
