I have some D1 code that I'm transfering to D2, and it's using getchar. I think I need to flush the buffer or something because the loop tends to skip:
import std.c.stdio;
import std.stdio;
void main()
{
char k;
for(int i = 0; i < 10; i++)
{
writef("Press key #%d:\t\n", i);
k = cast(char)getchar();
}
}
E.g.:
Press key #0:
a
Press key #1:
Press key #2:
b
Press key #3:
Press key #4:
c
Press key #5:
Press key #6:
I guess I could use scanf() instead.. or maybe something more D-ish perhaps? :)
Someone on the NGs started creating some user-friendly input functions, something like getInput!char(variable), or similar. But I can't find the topic, anyone know the link perhaps? It was fairly recent that someone posted it.
