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 Arduino 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 logical companion will -be highlighted. - - - -At present this feature is slightly buggy as the IDE will often -find (incorrectly) a brace in text that has been "commented out." - - - -Beginning programmers, and programmers coming to C from the BASIC -language often find using braces confusing or daunting. After all, -the same curly braces replace the RETURN statement in a subroutine -(function), the ENDIF statement in a conditional and the NEXT -statement in a FOR loop. - - - -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 carriage returns 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 often dramatically affect the meaning of a program. - - - -**The main uses of curly braces** ---------------------------------- - -Functions ---------- - -:: - - void myfunction(datatype argument){ - statements(s) - } - - - -Loops ------ - -:: - - while (boolean expression) - { - statement(s) - } - - do - { - statement(s) - } while (boolean expression); - - for (initialisation; termination condition; incrementing expr) - { - statement(s) - } - - - -Conditional statements ----------------------- - - - -:: - - if (boolean expression) - { - statement(s) - } - - else if (boolean expression) - { - statement(s) - } - else - { - statement(s) - } - - - -`Reference Home <http://arduino.cc/en/Reference/HomePage>`_ - |
