1. First, you need to define an array. Common array types are int type, float type, char character type and so on. You can define them by typing.

2. Then there is the name of the array, which can be defined by yourself, but it must conform to the corresponding rules.

3. Generally, the size of the array is determined at the definition stage of the array, and the input number is the size of the array, as shown in the figure below.

4. Then, you can initialize the array and enter it in curly braces.

5. If the number entered during initialization does not reach the defined length, it will be initialized to 0 by default.

6. Add semicolons after array definition and initialization, as shown in the figure below, and click Enter.
