Signed integer is any integer that carries negative sign while unsigned integer is any integer that carries positive sign
The largest unsigned integer is 26 - 1 = 63, giving the range 0 to 63; The largest signed integer is 25 - 1 = 31, giving the range -32 to 31.
a signed number is one that can be negative (have a sign) whereas an unsigned number will only be positive. due to less information, you can double the largest number storable in a signed integer to get the data available in an unsigned integer. However, PHP doesn't have unsigned integers, they're all signed.

Having an unsigned integer means that the integer is positive, and not negative; literally, the integer is unsigned and assumed to be positive. The unsigned integer 8 is positive-eight, not negative-eight.
What is the significance of declaring a constant unsigned integer?
if it is a signed int the the range is -32768 to 32767if its unsigned then 0 to 65535
Type size of an unsigned integer is compiler specific. Most compilers will provide 4 bytes, but the size can range from 2 to 8, or (again) whatever the implementation provides. Note: 1. Maximum value: UINT_MAX (in limits.h) 2. Size in bytes: sizeof (unsigned)
A 5-bit binary counter, interpreted as an unsigned integer, has a range of 0 to 31. Interpreted as a two's complement signed integer, it has a range of -16 to +15.
No. They are unsigned, therefore all representations are positive.
Consult your limits.h and math.h. For char it will be -128..127 or 0.255 (signed and unsigned).

An unsigned integer cannot be negative. It has a maximum positive value twice that of a signed integer. Max signed: 128 Max signed: 256 I could be off by one there, though.
