The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage. You can make a temporary magnet by stroking a piece of iron or steel (such as a needle) along a permanent magnet.

AleksandrR [38]

Answer:

#include <iostream>

using namespace std;

int * reverse(int a[],int n)//function to reverse the array.

{

   int i;

   for(i=0;i<n/2;i++)

   {

       int temp=a[i];

       a[i]=a[n-i-1];

       a[n-i-1]=temp;

   }

   return a;//return pointer to the array.

}

int main() {

   int array[50],* arr,N;//declaring three variables.

   cin>>N;//taking input of size..

   if(N>50||N<0)//if size greater than 50 or less than 0 then terminating the program..

   return 0;

   for(int i=0;i<N;i++)

   {

       cin>>array[i];//prompting array elements..

   }

   arr=reverse(array,N);//function call.

   for(int i=0;i<N;i++)

   cout<<arr[i]<<endl;//printing reversed array..

   cout<<endl;

return 0;

}

Output:-

Explanation:

I have created a function reverse which reverses the array and returns pointer to an array.I have also considered edge cases where the function terminates if the value of the N(size) is greater than 50 or less than 0.
