Hi everyone! I'm trying to do error handling (with the try

integer and I give a non-number value), then It doesn't let me
re get input. The code:
int x;
bool not_accepted = false;
while (!not_accepted) {
try {
write("x: ");
readf("%d\n", x);
not_accepted = true;
} catch (Exception msg) {
writeln("Please give a right coordinate");
}
Probably readf stops as soon as it encounters an error, meaning
that your input is still present.
Try instead getting a line via readln, and then trying to read
that into your expected input.

Thanks Steve! I will get the input a string then as you said and
then I'll try to convert it! Thanks a lot, have a nice day!
