List the conditional structures offered by a programming language. See Wikipedia: conditionals for descriptions.

Common conditional structures include if-then-else and switch.

Less common are arithmetic if, ternary operator and Hash-based conditionals.

Arithmetic if allows tight control over computed gotos, which optimizers have a hard time to figure out.



a = 3
if( a == 1 ){
    io.writeln( 'a == 1' )
}else if( a== 3 ){
    io.writeln( 'a == 3' )
}else{
    io.writeln( 'a is neither 1 nor 3' )
}
