C++ Data Types
Unsigned Data Types
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:
0if the number is non-negative;1if 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
#include <iostream> int main() { unsigned int total_vehicles = 1446000000; unsigned short age = 21; std::cout << total_vehicles << std::endl; std::cout << age << std::endl; }
Note
Additionally, there is a
signedtype modifier available to indicate that a data type can accommodate both positive and negative numbers. But all numerical data types by default aresigned, 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.
