	int *a,n,i,j,temp;

	printf("Enter size of array:");
	scanf("%d",&n);

	{

		scanf("%d",&a[i]);

	}

	
		
	for(i=0,j=n-1;i<j;i++,j--)
	
	{

		temp=a[i];
		a[i]=a[j];
		a[j]=temp;
	}

	printf("\After reversing the array:\n");
	for(i=0;i<n;i++)

	{

		printf("%d ",a[i]);

	}

	
	return 0;

}
			
				
			

Program Explanation

initialize i to first location of array and j to last location of array using i=0 j=n-1

swap the elements in location i and j, then increment i by 1 and decrement j by 1.

t=a[i] a[i]=a[j] a[j]=temp repeat the above step till i is less than j
