Algorithm to reverse an array

  1. First of all take number of elements as input from user. Let it be N.
  2. Then ask user to enter N numbers and store it in an array(lets call it inputArray).
  3. Declare another array of size equal to input array.
  4. Using a for loop, copy elements from inputArray to reverseArray in reverse order.

How do you reverse an array using recursion in C++?

The logic is simple, swap arr[start] with arr[end] then recursively call reverse for rest of the array.

If your array is initially 1 2 3 4 5 , here’s the sequence of swaps at each recursion step:

  1. swap 0 and 4 : 5 2 3 4 1.
  2. swap 0 and 3 : 4 2 3 5 1.
  3. swap 0 and 2 : 3 2 4 5 1.
  4. swap 0 and 1 : 2 3 4 5 1.

What is an array in C++ with example?

We will learn to declare, initialize, and access array elements in C++ programming with the help of examples. In C++, an array is a variable that can store multiple values of the same type. For example, Suppose a class has 27 students, and we need to store the grades of all of them.

How do you create an array in C++?

A typical declaration for an array in C++ is: type name [elements]; where type is a valid type (such as int , float …), name is a valid identifier and the elements field (which is always enclosed in square brackets [] ), specifies the length of the array in terms of the number of elements.
