5547Released 11mo ago100% Free### Example Calculation for a 2x2 Array in Row-Major Order in C Below is an example of a 2x2 array in row-major order in C, along with a calculation to access and display each element: ```c #include <stdio.h> int main() { // Declare a 2x2 array in row-major order int arr[2][2] = {{1, 2}, {3, 4}}; // Access and display each element for (int i = 0; i < 2; i++) { for (int j = 0; j < 2; j++) { printf("Element at arr[%d][%d] = %d\n", i, j, arr[i][j]); } } return 0; } ``` **Explanation:** * We declare a 2x2 array `arr` with elements `{1, 2}` in the first row and `{3, 4}` in the second row. * We use nested loops to access each element of the array. The outer loop iterates over the rows (`i`), and the inner loop iterates over the columns (`j`). * Inside the inner loop, we use `printf` to display the element at `arr[i][j]`, along with its corresponding row and column indices. * The output will be: ``` Element at arr[0][0] = 1 Element at arr[0][1] = 2 Element at arr[1][0] = 3 Element at arr[1][1] = 4 ``` **Key Concepts:** * **Row-Major Order:** In row-major order, elements are stored row by row, meaning that the elements of each row are contiguous in memory. This is the default storage order for arrays in C. * **Array Indexing:** In C, arrays are 0-indexed, meaning that the first element of an array is at index 0. * **Nested Loops:** We use nested loops to iterate over the elements of a 2D array. The outer loop iterates over the rows, and the inner loop iterates over the columns. This example demonstrates how to access and display elements of a 2x2 array in row-major order in C.
