Let's Learn D!

Hey /prog/! Today we're going to learn about the D programming language. Today's topic is array slices.


// main.d
void main() // Ok in D. The runtime handles main's return
{
    int[10] arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
    int[2] slice = arr[3..5];
    writeln(slice) // "[4, 5]"
}

Array slices in D capture a [bold]view[/bold] of the original array. They DO NOT create a copy.

In D, since strings are arrays of characters, the exact same syntax works with strings.


// main.d
int main() // int main() is fine as well
{          // but you must supply a return value
    string s = "Yo prog, I herd you liek programming";
    // $ is shorthand for the end index of the array
    string sslice = s[10..$];
    writeln(sslice); // "I herd you liek programming";

    sslice = "I herd you liek jews";
    writeln(sslice); // "I herd you liek jews"
    writeln(s); // "Yo prog, I herd you liek jews"

    return 0;
}

So as you can see, modifying a slice of an array also modifies the original array. Good luck coding!

Oh wow this is such a difficult concept, thanks for explaining it to me!

On a more serious note, fuck off back to /g/ you stupid piece of shit.
