Name
for statement — For loop statement
Synopsis
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.
Example
for
(int i = 0; i < 10; ++i) cout << i << '\n';for
(node* n = head; n != 0 ; n = n->next) link_node(n);
