}
this above c++ code is meant to find the reverse of the elements of array which is taken as input from user.Input data function is used to take input from the user.Display function is used to display that input.Then there is a function reverse which finds the reverse. But it does not gives proper reverse(output) e.g if i enter 5 array elements as 1,2,3,4,5 its output should be as 5,4,3,2,1.But this results as 5,4,3,4,5.
