Consider the following program:
import std.stdio;
void main(string[] args) {
int a, b, c;
while(true) {
readf("%d,%d,%d", &a, &b, &c);
writeln(a, b, c);
}
}
If I enter "5,5,5" on the commandline, hit enter, then enter
"5,5,5" a second time, hit enter again, the second time it
crashes. Why? What am I getting wrong here?
The error I am getting is the following:
std.conv.ConvException@/usr/include/dmd/phobos/std/conv.d(2002):
