What is the output of the following C code:#include <stdio.h>void fun(int **p);int main(){ int a[3][4] = {1, 2, 3, 4, 4, 3, 2, 8, 7, 8, 9, 0}; int *ptr; ptr = &a[0][0]; fun(&ptr); return 0;}void fun(int **p){ printf("%d\n", **p);}1234

The given code is written in C programming language. It declares a function fun that takes a double pointer p as a parameter. The main function initializes a 2D array a with some values and assigns the address of the first element of a to a pointer ptr. Then, it calls the fun function by passing the address of ptr as an argument. Finally, the fun function prints the value at the address pointed by p using double dereference operator **p.

The expected output of the given code is 1, as it will print the value at the address ptr, which is the first element of the 2D array a.
