Hi everyone! I'm trying to do error handling (with the try block) and
when I give a wrong value to the variable (it is an 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.
