A 2D array in C is an array of arrays. It is a data structure that represents a table-like structure with rows and columns. Each element in the 2D array is accessed using two indices: the row index and the column index. Here is an example of declaring and initializing a 2D array in C: #include int main() { int arr[3][4] = { {1 2 3 4} {5 6 7 8} {9 10 11 12} }; // Accessing elements in the 2D array printf(%d\n arr[0][0]); // Output: 1 printf(%d\n arr[1][2]); // Output: 7 printf(%d\n arr[2][3]); // Output: 12 return 0; } In this example we declare a 2D array `arr` with 3 rows and 4 columns. We initialize it with some values using the initializer list. The indexing starts from 0 so `arr[0][0]` refers to the first element in the array `arr[1][2]` refers to the element in the second row and third column and `arr[2][3]` refers to the element in the third row and fourth column. Note that the size of each dimension of the 2D array must be specified at the time of declaration.
