 |
|
| I am a total newbie, and I have no idea how to get an integer input. Or if I can just use 'readln()' and convert the char[] type to the desired type. |

Something like this:
| Code: | import std .conv ;
// ...
value = to!int( text ); |
to is your friend. ^_^ Depending on your usage, you might also want to look at parse, also from std.conv. Documentation:

Gives me this error  :
| Code: |
writef("Please type a number: ");
char[] input = readln();
input = to!int(input);
[color=red]
found '!' when expecting ';' following 'statement'
[/color]
|
[/code] |

I guess you are using D1.
Use toInt( input ) instead. You still import std.conv. |

I should really start making a point of asking that first... and of not assuming D2 when I answer... Oh well, sorry.
