# C Exercises: Reverse a given array of integers and length 5

## C-programming basic algorithm: Exercise-38 with Solution

Write a C program to reverse a given array of integers of length 5.

C Code:

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

// Function prototype for 'print_array'
void print_array(int parray[], int size);

int main(void){
// Declaration and initialization of variables
int arr_size;
int a1[] = {10, 20, 30, 40, 50};

// Calculating the size of the array
arr_size = sizeof(a1)/sizeof(a1[0]);

// Printing the original array
printf("Elements in original array are: ");
print_array(a1, arr_size);

// Creating a new array with elements in reverse order from the original array
int result[] = { a1[4], a1[3], a1[2], a1[1], a1[0] };

// Calculating the size of the new array
arr_size = sizeof(result)/sizeof(result[0]);

// Printing the reversed array
printf("\nElements in reverse array are: ");
print_array(result, arr_size);
}

// Definition of the 'print_array' function
void print_array(int parray[], int size)
{
int i;
for( i=0; i<size-1; i++)
{
// Printing each element with a comma and a space
printf("%d, ", parray[i]);
}
// Printing the last element without a comma and space
printf("%d ", parray[i]);
// Printing a new line to separate the elements
printf("\n");
}
``````

Sample Output:

```Elements in original array are: 10, 20, 30, 40, 50

Elements in reverse array are: 50, 40, 30, 20, 10
```
