Write a function that reverses the elements of an array in place. The function must accept only one pointer value and return void.

#include<iostream.h>

#include<conio.h>

class reverse

{

public:

int n;

reverse();

void rev(int* a);

};

reverse::reverse()

{

cout<<"enter the number of elements you want to store"<<endl;

cin>>n;

}

void reverse::rev(int* a)

{

cout<<"The reversed array is "<<endl;

for(int i=n-1;i>=0;i--)

cout<<a[i]<<endl;

}

int main()

{

clrscr();

reverse obj;

int* a1 ;

a1=new int[obj.n];

cout<<"enter the elements of the array "<<endl;

for(int i=0;i<obj.n;i++)

cin>>a1[i];

obj.rev(a1);

getch();

return 1;

}
