Data structures in Python and C , Series 5 : Reversing a array or list

C program to reverse an array

C program to reverse an array: This program reverses the array elements. For example, if 'A' is an array of integers with three elements such that

A[0] = 1, A[1] = 2, A[2] = 3

Then after reversing, the array will be

A[0] = 3, A[1] = 2, A[0] = 1

Given below is the C code to reverse an array.

#include<stdio.h>

int main()

{

 int array[100],n,c,temp;

 printf("enter the number of elements");

 scanf("%d",&n);

 for(c = 0;c <n;c++)

 {

  printf("enter the %d element",c);

  scanf("%d",&array[c]);

 }



 printf("now we are going to reverse the array by swapping");



 for(c =0; c<n/2 ;c++)

 {

  temp = array[c];

  array[c] = array[n-1-c];

  array[n-1 - c] = temp;

 }

 printf("the reversed array is ");

 for(c=0;c<n;c++)

 {

  printf("%d \n",array[c]);

 }

 return 0;

}

Python program to reverse an array:

Its very simple just if a list is :



a = [1,2,3,4,5]



a_rev = a[::-1]
