Within the function, a loop is used to iterate through each column of the matrix and swap the elements at corresponding positions in the two rows. Then in the main function, an array matrix and row indices row1 and row2 are defined, and the swapRows function is called to swap the elements of the two rows in the matrix. Finally, nested loops are used to print the swapped matrix. Running this code will output the swapped matrix.<\/p>\n<pre class=\"post-pre\"><code>4 5 6 \r\n1 2 3 \r\n7 8 9 \r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"<p>To swap two rows of a matrix, you need to iterate through each column and exchange the corresponding elements of the two rows.
