signed int

signed int是一种整数数据类型，用于存储带符号的整数值。它可以表示正数、负数和零。在大多数编程语言中，signed int通常占用4个字节（32位），其中一个位用于表示符号（正负）。

signed int的取值范围取决于具体的编程语言和操作系统，但通常范围为-2,147,483,648到2,147,483,647（包括这两个值）。

例如，在C语言中，可以使用关键字"int"来声明一个signed int变量，如下所示：

int x = -10;

在这个例子中，变量x被声明为一个signed int类型，并赋值为-10。这意味着x可以表示从-2,147,483,648到2,147,483,647之间的任何整数值。

signed int是什么

Signed integers, also known as signed types or simply signeds[^1], are integer data types that have a defined range that includes both positive and negative values. Unlike their unsigned counterparts, they include a special value called "zero" and a negative range to represent the absence of a positive number or a loss of magnitude. In programming languages like C and C++, `int` type by default is signed (often referred to as `signed int`), with a typical range of -2147483648 to 2147483647, which is half the size of its unsigned counterpart's range due to the inclusion of negative numbers. This means you can store more distinct values in an unsigned int compared to a signed int of the same bit width.
