Question

C++. Write a program that copies the contents of one array into another array but in reverse order using pointers.

          - in main()

                   - define 2 arrays of type int, 10 elements each

                             - initialize one array with numbers 1 through 10

                             - initialize all elements of the second array to 0

                   - call function reverseCopy with both arrays as arguments

                   - display the values of array number 2 (reversed order)

          - reverseCopy function

                   - use pointers ONLY to reference the elements of the arrays

                             - no array subscripts allowed!!!

                    - use a loop to copy the elements of array 1 into array 2

                             - in reverse order

                                      - element 10 of array 1 copied to element 1 of array 2

                                      - element 9 of array 1 copied to element 2 of array 2

                                      - and so on till all elements are copied

Answer 1

#include<stdio.h>

void reverseCopy(int arr1[10],int arr2[10])

{

int j=0;

for(int i=9;i>=0;i--)

{

*(arr2+j) = *(arr1+i);

j++;

}

  

printf("Content of array 2 : ");

for(int i=0;i<10;i++)

printf("%d ",*(arr2+i));

}

int main()

{

int arr1[10] = {1,2,3,4,5,6,7,8,9,10};

int arr2[10] = {0,0,0,0,0,0,0,0,0,0};

reverseCopy(arr1,arr2);

return 0;

}
