problem with data type

Hi :wave:
I tried to declare avariable tgelephoneNo as an int or long but dose not work when insert a numer like 01992 787878 it said int to large same as for the long, could you please tellme what is wrong

Is there a space, if so it is wrong.

You can't start with 0.

And also, maximum value of int is 2³² - 1. You exceeded that limit in int type.

In long type use postfix 'L' to indicate it is a long value.

Telephone numbers are strings not integers

Ya, if you want to add it with zero and space, better to make them as Strings.
