How do you define a two-dimensional array in C language?

In C language, you can use the following syntax to define a two-dimensional array:

数据类型 数组名[行数][列数];

In this case, the data type represents the type of data for each element in the array, the array name is an identifier used to refer to the array, the row number represents the number of rows in the two-dimensional array, and the column number represents the number of columns in the two-dimensional array.

For example, you can define a 3 by 4 integer two-dimensional array using the following statement:

int array[3][4];

This defines a two-dimensional array named “array” with 3 rows and 4 columns, where each element is of integer data type.
