Why is the range of unsigned int is from 0 to 65535?
Your compiler might NOT be 16-bit. Means, int is not 16 bits but 32 bits (4 bytes). That is why, it is going beyond 65535.
What is the data type that has a range of value from 0 to 65535?
Integer Types
| Type | Storage size | Value range |
|---|---|---|
| unsigned int | 2 or 4 bytes | 0 to 65,535 or 0 to 4,294,967,295 |
| short | 2 bytes | -32,768 to 32,767 |
| unsigned short | 2 bytes | 0 to 65,535 |
| long | 8 bytes or (4bytes for 32 bit OS) | -9223372036854775808 to 9223372036854775807 |
What is the significance of 65535?
In Internet protocols, 65535 is also the number of TCP and UDP ports available for use, since port 0 is reserved. In some implementations of Tiny BASIC, entering a command that divides any number by zero will return 65535.
What is the range of unsigned int?
0 to 4,294,967,295
In this article
| Type Name | Bytes | Range of Values |

| __int8 | 1 | -128 to 127 |
| unsigned __int8 | 1 | 0 to 255 |
| __int16 | 2 | -32,768 to 32,767 |
Does unsigned int include 0?
Unsigned Integers (often called “uints”) are just like integers (whole numbers) but have the property that they don’t have a + or – sign associated with them. Thus they are always non-negative (zero or positive).
Why do we write unsigned int before variable?
Unsigned int is usually used when we are dealing with bit values that means when we are performing bitwise operations like bit masking orbit shifting. As bit shifting in negative integers is undefined or implementation-defined outputs.
What is an unsigned integer and the range of values it can store?
Unsigned integers are integers that can only hold non-negative whole numbers. A 1-byte unsigned integer has a range of 0 to 255. Compare this to the 1-byte signed integer range of -128 to 127.
What is the result of 65536 >> 14?
In mathematics A 16-bit number can distinguish 65536 different possibilities. For example, unsigned binary notation exhausts all possible 16-bit codes in uniquely identifying the numbers 0 to 65535. In this scheme, 65536 is the least natural number that can not be represented with 16 bits.
Why do we need signed and unsigned integer?
Unsigned can hold a larger positive value and no negative value. Unsigned uses the leading bit as a part of the value, while the signed version uses the left-most-bit to identify if the number is positive or negative. Signed integers can hold both positive and negative numbers.
What are the signed int and unsigned int ranges?
A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a nonnegative integer in the range [0 to 4294967295].
