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.

Pointers and arrays have a close relationship in the C programming language. In fact, arrays can be thought of as a kind of pointer.

An array is a contiguous block of memory that stores multiple elements of the same data type. The elements in an array are accessed using an index that represents their position within the array. When an array is declared, the name of the array acts as a constant pointer to the first element of the array.

Pointers, on the other hand, are variables that store memory addresses. They can point to the address of another variable or object. In the case of arrays, a pointer can be used to access elements of the array.

To illustrate the relationship between pointers and arrays, let's consider an example:

#include <stdio.h>

int main() {
    int arr[5] = {1, 2, 3, 4, 5};
    int *ptr = arr; // Assigning the address of the first element to the pointer

    printf("Array elements using array syntax:\n");
    for (int i = 0; i < 5; i++) {
        printf("%d ", arr[i]);
    }

    printf("\nArray elements using pointer syntax:\n");
    for (int i ___ _____ _________ ____ ____ _______ _________ ____.
