This tutorial lists all the possible approaches to reversing an array in C. For example, Suppose given an array: We need to reverse the array and print the following: We can use list slicing in Python and specify the step as -1 -> list [::-1] to get the reversed list. In C, there is no slicing mechanism.
3 days ago · 1. Array Reverse Using an Extra Array (Non In-place): Create a new array of the same size as the original array. Copy elements from the original array to the new array in reverse order. Below is the implementation of the above approach: C++
Jul 31, 2023 · In this article, we will learn to write a C program to reverse an array. Reversing an array means changing the order of elements so that the first element becomes the last element and the second element becomes the second last element and so on.
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 on reversing the array will be. a [0] = 3. a [1] = 2. a [0] = 1. Given below is the c code to reverse an array. Example: Copy Code.
Dec 18, 2022 · In C, there are no inbuilt functions to reverse an array, we have to write the code for it on our own. An array can be reversed using different methods and algorithms - printing it from the last element, using an auxiliary array, recursion, swapping, etc.
In this article we show you, How to write a C Program to Reverse an Array using While Loop, For Loop, Functions and Recursions with example. Skip to content Menu
Mar 5, 2021 · Reversing array in C. We can reverse array by using swapping technique. For example, if 'P' is an array of integers with four elements −. P[0] = 1, P[1] = 2, P[2] = 3 and P[3]=4. Then, after reversing −. P[0] = 4, P[1] = 3, P[2] = 2 and P[3]=1.
Reverse array in C. C program to reverse an array using an additional array, using swapping and by using a function. 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.
Sep 2, 2023 · C program to reverse an array elements - Suppose we have an array with n elements. We shall have to reverse the elements present in the array and display them. (Do not print them in reverse order, reverse elements in place).So, if the input is like n = 6 arr = [9, 8, 7, 2, 4, 3], then the output will be [3,4,2,7,8,9]To solve this, we will
Apr 30, 2021 · Reverse an array in C. In this post, we will see how to reverse an array in C in linear time. 1. Using Auxiliary Array. A simple solution is to create an auxiliary array of the same type and size as the input array, fill it with elements from the input array backward, and then copy the auxiliary array’s contents into the original one.
