C program to read an array and print its reverse using pointers?

Answer 1

#include<stdio.h>

#include<conio.h>

// note: this code does not test for user-input errors!!

int main() {

int array[10],i,n;

printf("enter the number of elements in the array:");

scanf("%d",&n);

for(i=0;i<n;i++) scanf("%d",&array[i]);

printf("the reverse ordered array is :");

for(i=n-1;i>=0;i--) printf("%d",array[i]);

return 0;

}

Answer 2

01 #include 02#include

03#include

04

05 int main()

06{

07 int *ptr,i,n;

08 clrscr();

09 printf("Enter the no of elements:");

10 scanf("%d",&n);

11 ptr=(int *)malloc(sizeof(int)*n);

12 if(ptr==NULL)

13 {

14 printf("Not enough memory");

15 exit(1);

16 }

17 for(i=0; i

18 {

19 printf("Enter %d element : ",i+1);

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

21 }

22 printf("Array in original order\n");

23 for(i=0; i

24 {

25 printf("%d\n",ptr[i]);

26 }

27 printf("Array in reverse order\n");

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

29 {

30 printf("%d\n",ptr[i]);

31 }

32 getch();

33 return 0;

34 }

Answer 3

#include #include #define MAX 30 void main() { int size,i,arr[MAX]; int *ptr; clrscr(); ptr=&arr[0]; printf("Enter the size of array : "); scanf("%d",&size); printf("nEnter %d integers into array:n",size); for(i=0;ifor(i=size-1;i>=0;i--) { printf("nElement%d is %d :",i,*ptr); ptr--; } getch(); }

Answer 4

Get the Array Elements. Create another array. Using loops, copy the values reversely.
