Write a function that reverses the contents of an array of double and test it in

Question

Write a function that reverses the contents of an array of double and test it in a simple program.

GIVEN CODE:

#include <stdio.h>
#include <stdlib.h>

void PrintArray(int *a, int size)
{
int i;

for (i = 0; i < size; i++)
printf("%d ", *(a+i));

printf(" ");   
}

int main()
{
int *pa;
int size;
int i, j;
int temp;

printf("Data size: ");
scanf("%d", &size);

if (size < 1)
return -1;
  
  
pa = (int*) malloc( size * sizeof(int));
if (pa == NULL){
printf(" Error ");
return -2;
}
for (i = 0; i < size; i++)
scanf("%d", (pa + i));

printf(" Array: ");
PrintArray(pa, size);

// Reverses the Array Here

printf(" New Array ");
PrintArray(pa, size);   
free(pa);

return 0;

}

Explanation / Answer

#include <stdio.h>
#include <stdlib.h>

void PrintArray(int *a, int size)
{
   int i;

   for (i = 0; i < size; i++)
      printf("%d ", *(a+i));

   printf(" ");
}

int main()
{
   int   *pa,*z;
   int   size;
   int   i, j;
   int   temp;

   printf("Data size: ");
   scanf("%d", &size);

   if (size < 1)
      return -1;
    
    
   pa = (int*) malloc( size * sizeof(int));
   if (pa == NULL){
      printf(" Error ");
      return -2;
   }
   for (i = 0; i < size; i++)
      scanf("%d", (pa + i));

   printf(" Array: ");
   PrintArray(pa, size);

   // Reverses the Array Here
     z = (int*) malloc( size * sizeof(int));
   for(i=1;i<=size;i++)
   {
      z[size-i]=pa[i-1];
             
    }
    pa=z;
   printf(" New Array ");
   PrintArray(pa, size);
   free(pa);

   return 0;

}
