# C Exercises: Print the elements of an array in reverse order

## C Pointer : Exercise-17 with Solution

Write a program in C to print the elements of an array in reverse order.

Visual Presentation:

Sample Solution:

C Code:

``````#include <stdio.h>

int main() {
// Declaring variables
int n, i, arr1[15];
int *pt;

// Displaying the purpose of the program
printf("\n\n Pointer : Print the elements of an array in reverse order :\n");
printf("----------------------------------------------------------------\n");

// Inputting the number of elements for the array (maximum 15)
printf(" Input the number of elements to store in the array (max 15) : ");
scanf("%d", &n);

pt = &arr1[0];  // pt stores the address of base array arr1

// Inputting elements into the array using pointers
printf(" Input %d number of elements in the array : \n", n);
for (i = 0; i < n; i++) {
printf(" element - %d : ", i + 1);
scanf("%d", pt); // Accepting the address of the value
pt++;
}

pt = &arr1[n - 1]; // Setting pt to point at the last element of the array

// Displaying the elements of the array in reverse order using pointers
printf("\n The elements of array in reverse order are :");
for (i = n; i > 0; i--) {
printf("\n element - %d : %d  ", i, *pt); // Printing the element and its value
pt--; // Moving the pointer to the previous element
}

printf("\n\n");
}
```
```

Sample Output:

``` Pointer : Print the elements of an array in reverse order :
----------------------------------------------------------------
Input the number of elements to store in the array (max 15) : 5
Input 5 number of elements in the array :
element - 1 : 2
element - 2 : 3
element - 3 : 4
element - 4 : 5
element - 5 : 6

The elements of array in reverse order are :
element - 5 : 6
element - 4 : 5
element - 3 : 4
element - 2 : 3
element - 1 : 2
```
