Such as this:

char[] text = "This is a test sentence.";

int loc = 5;

char num5 = text.getCharAt(loc);

Something along those lines.

Why not just do:

char[] text = "some text";
char num5 = text[5];

Just use

char num5 = text[loc-1];

Because it isn't working for me. That was what I was trying to do seeing as char[] is simply an array of characters. However, it's returning an int and not a char.

How about a little more code. What I've seen so far should work.

import std.stdio;

void main()
{
    char[] text = "this is a sentence";
    int loc = 5;
    writefln("%s", typeid(typeof(text[loc])));
}

this prints 'char' as expected...

text[5] will return the sixth element in the array.

He never said anything about getCharAt starting at one...
