C Program to Read and write an array using the pointer and function

Array elements can be accessed by using names and index. index 0 will point to base address of the array that is pointed using pointer. here, we can develop a program to access array elements using pointer referring to base address and function.

#include<stdio.h>
void read(int *p);
void display(int *q);
int main()
{
   int a[5];
   read( &a[0] );
   display( &a[0] );
   return 0;
}
void read(int *p)
{
   int i;
   printf("Enter array elements: ");
   for(i=0;i<5;i++)
   {
      scanf("%d",p+i);
   }
}
void display(int *q)
{
   int i;
   printf("Array elements are:\n");
   for(i=0;i<5;i++)
   {
      printf("%d\t",*(q+i));
   }
}

Output:

Enter array elements: 45
87
91
449
90
Array elements are:
45 87 91 449 90
