c program to reverse an array

c program to reverse an array :- This program reverses the array elements. For example if a is an array of integers with three elements
such that
a[0] = 1
a[1] = 2
a[2] = 3
then on reversing the array will be
a[0] = 3
a[1] = 2
a[0] = 1
In the program swapping is done to reverse the array elements. Simple or alternative method to reverse array elements is given in comments below.
Given below is the c code to reverse an array .

#include<stdio.h>

#include<conio.h>

main()

{

   int n, c, j, temp, a[100];

   printf("Enter the number of elements in array\n");

   scanf("%d",&n);

   printf("Enter the array elements\n");

   for ( c = 0 ; c < n ; c++ )

      scanf("%d",&a[c]);

   if( n%2 == 0 )

      c = n/2 - 1;

   else

      c = n/2;

   for ( j = 0 ; j < c ; j++ )

   {

      temp = a[j];

      a[j] = a[n -j - 1];

      a[n-j-1] = temp;

   }

   printf("Reverse array is\n");

   for( c = 0 ; c < n ; c++ )

      printf("%d\n", a[c]);

   getch();

   return 0;

}
