Briefly discuss the relation between pointers and arrays, giving suitable example. Write a program in C, to print transpose of a 2D matrix entered by a user. Also give comments.

In programming languages like C and Python, pointers and arrays have a closely intertwined relationship. While Python handles arrays differently than C, it’s important to understand how the concept of pointers works in C and how it relates to arrays.

### Relation between Pointers and Arrays in C:

In C, arrays and pointers are closely related. An array is essentially a block of contiguous memory locations, and a pointer is a variable that stores the address of another variable, including the address of the first element of an array.

When we declare an array in C, for example:

```c
int arr[5] = {1, 2, 3, 4, 5};
```

Here, `arr` is not just an array but also acts like a pointer to the first element of the array. In fact, the name of the array `arr` is equivalent to a pointer to the first element of the array. This means that the expression `arr` is pointing to the first element of the array `arr[0]`.

In C, we can use pointers to access elements of the array. For example:

```c
int *ptr = arr;  // Pointer ptr ___ ___ _________ _______ ________ ___ _____ ___.
