import std.stdio;
void main()
{
    uint guesses=0, high=100, low=0, guess=50;
    char returned;
    writef("Please choose a number between %s and %s.\n");
    writef("Press enter to begin.",low,high);
    readln();
    checkLoop:
    do {
        guess = (high-low)/2+low; // Avoid overflow (shouldn't occur)
        writef("Is your number %s? [(y)es, (h)igher, (l)ower] ", guess);
        readf("%c", &returned);
        readln();
        switch(returned) {
            case 'y','Y': break checkLoop;
            case 'h','H': {low=guess; break;}
            case 'l','L': {high=guess; break;}
            default: break;
        }
    } while(++guesses);
    writef("I guessed your number in %s moves!\n", guesses);
}

This piece is something I wrote quickly for /r/dailyprogrammer (By the 
way, is the person who has been posting D solutions to that on here?)
It's a really simple piece, but it shows %s, breaking from a loop from 
inside a switch, etc.
