for statement — For loop statement
statement := for ( for-init-stmt [condition] ; [expression] ) statement for-init-stmt ::= expression-stmt | simple-decl condition ::= expression | type-specifier-seq declarator = assignment-expr
The for
loop is used for
bounded loops and for unbounded loops that have well-defined
iterations. Execution starts with for-init-stmt
, which can be an expression
statement or a declaration. (Note that the syntax for expression-stmt
and simple-decl
both include a terminating
semicolon.)
condition
is then
evaluated. If condition
evaluates
to true, statement
is executed.
The iteration expression
is then
evaluated, and the condition
is
tested again. When condition
is
false, the loop ends and control passes to the statement following the
end of the for
statement
.
Declarations in for-int-stmt
and condition
are in the same scope as
expression and statement
. A continue
statement inside statement
transfers control to the
evaluation of the iteration expression
.
