c - is a compound literal not a literal? -


from c in nutshell:

chapter 3 literals

in c source code, a literal token denotes a fixed value, may integer, floating-point number, character, or string. literal’s type determined value , notation.

the literals discussed here different compound literals, introduced in c99 standard. compound literals ordinary modifiable objects, similar variables. full description of compound literals , special operator used create them, see chapter 5.

so literal has fixed value, i.e. value can't modified, while compound literal has modifiable values.

according that, 1 correct:

  • a compound literal not literal, or
  • the definition of literal should extended include compound literal becomes 1 exception fixed-value rule?

thanks.

the c11 standard never defines "literal" on own. speaks of "string literal" , "compound literal" individually.

tokens such 0, 0.0, a in enum { }, , '\0' called "constants" collectively, , "integer constants", "floating-point constants", "enumeration constants", , "character constants" respectively.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
