7.1 The if statement
The if statement is used for conditional execution:
-
It selects exactly one of the suites by evaluating the expressions one
by one until one is found to be true (see section 5.10 for
the definition of true and false); then that suite is executed (and no
other part of the if statement is executed or evaluated). If
all expressions are false, the suite of the else clause, if
present, is executed.
Release 2.4.5, documentation updated on 18 October 2006.
