C Program to Access elements of an array using pointer

What are Pointers?

A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address.

The general form of a pointer variable declaration is −

• type *var-name;

Here, type is the pointer’s base type; it must be a valid C data type and var-name is the name of the pointer variable.

The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used to designate a variable as a pointer.

The unary or monadic operator & gives the “address of a variable’”.

The indirection or dereference operator * gives the “contents of an object pointed to by a pointer”.

Below is the source code for C Program to Access elements of an array using pointer which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C Program to Access elements of an array using pointer  */

#include <stdio.h>

int main()
{
   int data[5], i;
   printf("Enter 5 elements below :: \n");

   for(i = 0; i < 5; ++i)
   {
       printf("\nEnter %d element :: ",i+1);
       scanf("%d", data + i);

   }

   printf("\nNumbers Entered are :: \n");
   for(i = 0; i < 5; ++i)
   {

       printf("\nElement %d = %d\n",i+1,*(data + i));

   }


   return 0;
}

Output : :

/*  C Program to Access elements of an array using pointer  */

Enter 5 elements below ::

Enter 1 element :: 7

Enter 2 element :: 2

Enter 3 element :: 5

Enter 4 element :: 1

Enter 5 element :: 4

Numbers Entered are ::

Element 1 = 7

Element 2 = 2

Element 3 = 5

Element 4 = 1

Element 5 = 4

Process returned 0
