C program to reverse an array.
#include <stdio.h>
int main()
{
int n, c, d, a[100], b[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]);
/*
* Copying elements into array b starting from end of array a
*/
for (c = n - 1, d = 0; c >= 0; c--, d++)
b[d] = a[c];
/*
* Copying reversed array into original.
* Here we are modifying original array, this is optional.
*/
for (c = 0; c < n; c++)
a[c] = b[c];
printf("Reverse array is\n");
for (c = 0; c < n; c++)
printf("%d\n", a[c]);
return 0;
}
Output:-
