C++ Program To Reverse An Array In O(n) Complexity

Problem :- Write A C++ Program To Reverse An Array In O(n);

ARRAY :- Array act to store related data under a single variable name with an index, also known as a subscript. It is easiest to think of an array as simply a list or ordered grouping for variables of the same type. As such, arrays often help a programmer organize collections of data efficiently and intuitively.

Solution :-

using namespace std;
int main()
  int *a;
  int i,j,temp;
  int n;
  cout<<"Enter The Size of Array \n";
  a=new int[n];
  int l=0,h=n-1;
cout<<"Enter The Elements of Array \n";
cout<<"\nReverse Array Is\n";
  cout<<a[i]<<" ";
   return 0;

Output :-
