Arrays DS in C/C++ - HackerRank Data Structures Solutions in C/C++ 

HackerRank solution in C and C++ for Arrays - DS. This HackerRank problem solving exercise consists of reversing an array of integers. The aim is not to sort the array, but simply to swap the values at different indices in the array to rearrange it backwards. That is how to reverse an array in C or C++, for this coding challenge.
In the C solution, we will create a variable to loop through the array until its middle position, and swap the values in a for loop through a temporary variable. In the C++ solution, we will do something similar, except that we will use the built-in swap function in C++ from the algorithm header to perform the swapping of values in the array. When we are done, we will return the array by reference.
Arrays are important data structures which are important to master both in C and C++ for competitive programming purposes.
