-Curly Braces (``{``, ``}``)
-===========================

-Introduction
-------------
-
-Curly braces (also referred to as just "braces" or as "curly
-brackets") are a major part of the C and C++ programming
-languages. They are used in several different constructs, outlined
-below, and this can sometimes be confusing for beginners.
-
-An opening curly brace, ``{`` must always be followed by a closing
-curly brace ``}``. This is a condition that is often referred to as
-the braces being *balanced*. The Maple IDE (integrated development
-environment) includes a convenient feature to check the balance of
-curly braces. Just select a brace, or even click the insertion point
-immediately following a brace, and its companion will be highlighted\
-[#fbug]_\ .
-
-Beginning programmers, and programmers coming to C++ from languages
-without braces, often find using them confusing or daunting.
-
-Because the use of the curly brace is so varied, it is good
-programming practice to type the closing brace immediately after
-typing the opening brace when inserting a construct which requires
-curly braces. Then insert some blank lines between your braces and
-begin inserting statements. Your braces, and your attitude, will never
-become unbalanced.
-
-Unbalanced braces can often lead to cryptic, impenetrable compiler
-errors that can sometimes be hard to track down in a large program.
-Because of their varied usages, braces are also incredibly important
-to the syntax of a program and moving a brace one or two lines will
-usually dramatically affect the meaning of a program.

-The main uses of curly braces
------------------------------
-
-**Functions**::
-
- // a function body needs braces around it
- void myFunction(datatype argument) {
- // ... function body goes in here ...
- }
-
-**Loops** (see the :ref:`while <lang-while>`\ , :ref:`for
-<lang-for>`\ , and :ref:`do/while <lang-dowhile>` loop reference
-pages for more information)::
-
- // you should put braces around the body of a loop:
-
- while (boolean expression) {
- // code inside the loop goes here
- }
-
- for (initialisation; termination condition; incrementing expr) {
- // code inside the loop goes here
- }
-
- do {
- // code inside the loop goes here
- } while (boolean expression);
-
-
-**Conditional statements** (see the :ref:`if statement <lang-if>`
-reference page for more information)::
-
- // you should put braces around the body of an "if", "else if",
- // or "else":
-
- if (boolean expression) {
- // code inside the "if"
- }
- else if (boolean expression) {
- // code inside the "else if"
- }
- else {
- // code inside the "else"
- }
-
-**Switch statements** (see the :ref:`switch statement
-<lang-switchcase>` reference page for more information)::
-
- switch (var) {
- case 1:
- doThing1();
- break;
- case 2:
- doThing2();
- break;
- }

-
-.. TODO remove this once IDE 0.1.0 released
-
-.. [#fbug] At present this feature is slightly buggy as the IDE will
- often find (incorrectly) a brace in text that has been commented
- out.
