constructs / switch

Edit on Github

  • The switch statement. The LPC switch statement is nearly identical to the C switch statement. The only real difference is that the cases of the LPC switch may be strings as well as integers. Syntax is as follows:

switch (expression) { case constant0 : statements0; break; case constant1 : statements1; break; default : statements2; break; }

The switch is a replacement for the chained if else if else if else construct. The above switch is equivalent to:

tmp = expression; if (tmp == constant0) { statements0; …; } else if (tmp == constant1) { statements1; …; } else { statements2; …; }

The main difference between the switch and the if statement is that if the “break;” statement is ommited from the end of a particular case, then the statements in the next case will be executed as well.
