digitalmars.D - Problem while copy Array Element to variable

My Dynamic array completely work good but when assign it's one 
index to a variable, it's saves ASCII of that index.
writeln(myarray); // output 24
var = myarray[0]; // it assign 50 to var
Why changed to ASCII and how to get rid of.

First, just to remind you that this question would be more helpful on the Learn forum. :) You're not showing any code so I try to reproduce the issue: import std.stdio; void main() { auto myarray = "24"; writeln(myarray); // output 24 int var; auto var = myarray[0]; // it assign 50 to var writeln(var); } myarray[0] has the value 50 because 50 is the ASCII code of '2'. The reason var gets 50 in the above scenario is because var is an int. If you want to get char '2' (of course still with the value 50), you can make it char: char var; On the other hand, if you want to get the integer value 2, there is the trick of subtracting the value of '0' from it: var = myarray[0] - '0'; var now has value 2.

Remove that 'auto' please. Apparently, I edited my message instead of code. :p Ali

I got this with var = myarray[0] - '0'; without this I have to manually pollute my code. Thanks for Solution & also for writing Book on D Lang.
