Nobody mentioned the use of goto with switch-case.
http://ddili.org/ders/d.en/switch_case.html
goto can appear in three ways under case sections:
* 'goto case' causes the execution to continue to the next case.
* 'goto default' causes the execution to continue to the default section.
* 'goto expression' causes the execution to continue to the case that
matches that expression.
The following program demonstrates these three uses by taking advantage
of a foreach loop:
import std.stdio;
void main()
{
foreach (value; [ 1, 2, 3, 10, 20 ]) {
writefln("--- value: %s ---", value);
switch (value) {
case 1:
writeln("case 1");
goto case;
case 2:
writeln("case 2");
goto case 10;
case 3:
writeln("case 3");
goto default;
case 10:
writeln("case 10");
break;
default:
writeln("default");
break;
}
}
}
The output:
--- value: 1 ---
case 1
case 2
case 10
--- value: 2 ---
case 2
case 10
--- value: 3 ---
case 3
default
--- value: 10 ---
case 10
--- value: 20 ---
default
