How to create an array in C language?

In C language, you can create arrays using the following syntax:

1. Declare the type and name of the array, and specify the size of the array using square brackets [].

dataType arrayName[arraySize];

1. For example, create an array containing 5 integers.

int numbers[5];

1. It is possible to initialize an array when declaring it.

int numbers[5] = {1, 2, 3, 4, 5};

1. You can also declare the array first, and then assign values to it one by one.

int numbers[5];
numbers[0] = 1;
numbers[1] = 2;
numbers[2] = 3;
numbers[3] = 4;
numbers[4] = 5;

1. Array indexes start from 0, and you can access elements in the array using square brackets and the index value.

int x = numbers[0]; // 获取第一个元素
numbers[1] = 10; // 修改第二个元素

This is the basic way of creating an array in C language. Note that the size of the array must be determined at compile time and cannot be changed.
