In C language, two methods can be used to pass a two-dimensional array as a parameter to a function:<\/p>\n

    \n
  1. Passing arrays using pointers.<\/li>\n
  2. Pass the address of the first element of the 2D array as a parameter to the function.<\/li>\n
  3. Access array elements through pointer operations in the function.<\/li>\n
  4. The sample code is as follows:<\/li>\n
  5. void func(int (*arr)[M], int row, int col) {
    \n \/\/ Access array elements using pointers
    \n for (int i = 0; i < row; i++) {\n for (int j = 0; j < col; j++) {\n printf(\"%d \", arr[i][j]);\n }\n printf(\"\\n\");\n }\n}\n\nint main() {\n int arr[N][M] = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9} };\n int row = N;\n int col = M;\n\n \/\/ Pass the array's base address as a parameter to the function\n func(arr, row, col);\n\n return 0;\n}<\/li>\n
  6. Passing an array using a one-dimensional array:<\/li>\n
  7. Convert a two-dimensional array into a one-dimensional array.<\/li>\n
  8. Pass the address of the first element of a one-dimensional array as a parameter to the function.<\/li>\n
  9. In a function, accessing array elements is done by computing the index.<\/li>\n
  10. Here is the example code:<\/li>\n
  11. void func(int *arr, int row, int col) {
    \n \/\/ Access array elements using index calculation
    \n for (int i = 0; i < row; i++) {\n for (int j = 0; j < col; j++) {\n printf(\"%d \", arr[i * col + j]);\n }\n printf(\"\\n\");\n }\n}\n\nint main() {\n int arr[N][M] = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9} };\n int row = N;\n int col = M;\n\n \/\/ Convert the 2D array to a 1D array and pass the array's address as a parameter to the function\n func((int *)arr, row, col);\n\n return 0;\n}<\/li>\n<\/ol>\n

    Both methods can be used to pass a two-dimensional array as a parameter to a function, the choice depends on the specific needs and programming habits.<\/p>\n","protected":false},"excerpt":{"rendered":"
