Sep 25, 2024 · Given an array arr [], the task is to reverse the array. Reversing an array means rearranging the elements such that the first element becomes the last, the second element becomes second last and so on. Examples: Explanation: The first element 1 moves to last position, the second element 4 moves to second-last and so on.

I would use the reverse() function from the <algorithm> library. Run it online: repl.it/@abranhe/Reverse-Array. #include <iostream> #include <algorithm> using namespace std; int main() { int arr [10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; reverse(begin(arr), end(arr)); for(auto item:arr) { cout << item << " "; } } Output:

There are multiple ways to reverse an array in C++. Let’s discuss each of them. The idea is to create a new array and assign elements to it from the input array in reversed order. To do this, we simply have to: Initialize an array with values. Declare a new empty array of the same size.

Nov 20, 2021 · This post will discuss how to reverse an array in C++. The recommended solution for reversing elements of the specified array is to use the `reverse()` method defined in the `algorithm` header file.

To reverse an array in C++ programming, you have to ask the user to enter the array's size and then add elements (of the given size) to the array. Now to reverse, do these things: Move the element at the first index to the last, and the element at the last index to the first.

May 11, 2023 · Arrays can be reversed using the built-in reverse function in C++. Use the reverse function and supply the starting and ending addresses of the array as arguments. Syntax: reverse(arr,arr+n) will reverse the array arr of n elements. Code Implementation in C++. Output:

Mar 17, 2025 · Let's create a program to reverse the elements of the array using for loop in C++. Program1.cpp. Output. Enter the element 1: 78. Enter the element 2: 12. Enter the element 3: 54. Enter the element 4: 24. Enter the element 5: 7. Enter the element 6: …

Nov 15, 2024 · In this article, we will learn how to reverse an array using STL in C++. The most efficient way to reverse an array using STL is by using reverse () function. Let’s take a look at a simple example: This method reverses the array in-place i.e. it modifies the original array and rearranges it in reverse order.

Mar 12, 2025 · This article demonstrates how to reverse an array in C++. Explore various methods including loops, the STL's `std::reverse`, and recursion. Learn through clear examples and detailed explanations to enhance your C++ programming skills.

To reverse an array in C++, you can use a simple loop to swap elements from both ends of the array until you reach the middle. Here's a code snippet demonstrating this: void reverseArray(int arr[], int n) { for (int i = 0; i < n / 2; i++) { swap (arr[i], arr[n - i - …
