Quiz: What does the following code compute?
import std.stdio;
import core.exception;
void main(){
int a,b;
int[int] aa;
scanf("%d %d",&a,&b);
try{aa[a]=aa[b];printf("Y\n");}catch(RangeError){printf("N\n");}
}
What was your point here? Is there even any way an associative array
throws a RangeError?
An AA throws a range error if the key is not in the AA during an index
operation. Since aa is initialized, aa[b] would be expected to throw a
range error.
Duh me, of course. For a moment I thought that wasn't the case, I ran a
snippet to test that and no RangeError was thrown. But it turns out what
I had ran was the old version of the code, not the new one that I
modified and thought was running.
