how to pass 2d array to a function as an argument

There are 3 ways to pass 2D array to a function:

  1. you need to specify the no of columns in each row
    void passFunc(int a[][10])
    {
    // …
    }

in main, you’ll write:
passFunc(array);

  1. passing as an array of pointers, here also you need to specify the no of columns in each row
    void passFunc(int *a[10])
    {
    // …
    }

in main function you call it like:
int *array[10];
for(int i = 0; i < 10; i++)
array[i] = new int[10];
passFunc(array);

  1. You can pass a 2D array as a pointer to a pointer:
    void passFunc(int **a)
    {
    // …
    }

inside main function, you can call the function like:
int **array;
array = new int *[10];
for(int i = 0; i <10; i++)
array[i] = new int[10];
passFunc(array);
