How to use short in c language

In C language, short is a short integer data type, used to store integers with a smaller range than int, occupying 2 bytes of memory space, with a common range of -32,768 to 32,767. Purposes include saving memory and improving efficiency, but it has a smaller range and cannot represent unsigned values.

Usage of short in C language

Answer the question:

In C language, short is a short integer data type, used to represent integers smaller than the range of int.

Detailed expansion:

The short data type occupies 2 bytes of memory space, and its range varies according to the machine architecture. A common range is -32,768 to 32,767.

Purpose:

• When you need to store integers smaller than the int range, use short to save memory space.
• Short can also improve efficiency when large amounts of data need to be processed, because the data can be stored more compactly.

Limitations:

• Compared with int, short has a limited range and is therefore not suitable for storing larger integers.
• short is a signed integer, which means it cannot represent an unsigned value.

Example:

<code class="c">#include <stdio.h>

int main() {
    short x = 10; // 声明一个短整型变量 x
    int y = 20; // 声明一个整型变量 y

    printf("short x: %d\n", x); // 输出 x 的值
    printf("int y: %d\n", y); // 输出 y 的值
    return 0;
}</code>

Output:

<code>short x: 10
int y: 20</code>

In the above example, x is declared as a short type variable, and y is declared as an int type variable. When you print the values ​​of these variables, you can see that x has a smaller range of -32,768 to 32,767, while y has a larger range of -2,147,483,648 to 2,147,483,647.
