C++ int length
WebSep 8, 2011 · int x; cin >> x; int lengthCount = 0 for(; x != 0; x /= 10, lengthCount++); It keeps dividing by 10, and as long as the number is not 0 it will add to the count and then divide by 10 again. If the user enters 0, it reports the length as zero, for all other single digit numbers it would report it as 1.

It is a compile-time execution operator. ... // &arr returns a pointer int size = *(&arr + 1) - arr; How does this work? Here the pointer arithmetic does its part. We don’t need to explicitly convert each of the locations to character pointers.
