What data type does uint belong to?

This article introduces the relevant knowledge of "what data type uint belongs to". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The UINT type, defined in "WINDOWS API", corresponds to a 32-bit unsigned integer; the value of an unsigned integer is "2 ^ 31-1", that is, "zero 4294967295". Unsigned values can avoid mistakenly storing negative numbers and expand the range of representation.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The UINT type, defined in WINDOWS API, corresponds to a 32-bit unsigned integer.

Unsigned integer (unsigned int): the value is 2 ^ 31-1, that is, 0 ^ 4294967295

Take the decimal 32767 (all of the following examples take this number as an example), its binary is:

0111 1111 1111 1111

For the unsigned integer 32767, the highest bit of its binary is called the data bit, that is, the 0 is the data bit, and the data bit is to participate in the operation. If we change 0 to 1, that is, 16 1s, its decimal system is 65535 (that is, 2 to the 15 + 2 to the 14. All the way up to the zero power of 2), which is different from signed integers.

The root cause of whether there is a sign or not can be said to be caused by the overflow of the data.

Unsigned values can avoid mistakenly storing negative numbers and expand the range of representation.

Such as:

Unsigned tinyint 1 has no symbolic value within the age of 150: 0 to 255.

Tortoise hundreds of years old unsigned smallint 2 has no symbolic value: 0 to 65535.

Dinosaur fossils are tens of millions of years old. Unsigned int 4 has no symbolic value: 0 to about 4.29 billion.

The sun has an unsigned value of unsigned bigint 8 for about 5 billion years: 0 to the 19th power of about 10.

Extended data:

The keyword UINT does not exist in C, C++.

The UINT type is derived from unsigned int

Int is signed and ranges from-2147483648 to 2147483647

Uint is an unsigned integer, indicating a range of 0 to 42949 67295 (2 ^ 32-1), that is, the first number does not represent a symbol

In C #, uint is the keyword

Represents an integer type that stores values based on the size and range shown in the following table
