C++ Data Types

## C++ Data Types

# Unsigned

To represent a number in the binary system, it is necessary to store both its **value** and **sign**. One bit is dedicated to storing the sign, while the remaining bits are used to store the numerical value. The sign bit stores:

`0`

if the number is non-negative;`1`

if the number is negative.

If we are certain that our variable can **only hold non-negative numbers**, we can utilize the `unsigned`

type modifier. This modifier enables the storage of values without considering the sign.

Moreover, due to the increased memory available for storing the value, the range of possible values is wider; however, negative numbers are not included within this range. Therefore, the allowed ranges are as follows:

main

Note

Additionally, there is a

`signed`

type modifier available to indicate that a data type can accommodate both positive and negative numbers. But all numerical data types by default are`signed`

, so there is no need to specify it explicitly.

Be sure to use `unsigned`

only when the variable can not take negative numbers.

Assigning a negative value to an unsigned variable will not produce any errors, but the resulting value will be incorrect. Your task is to check this statement yourself!
