Array of Pointer
Arrays of pointers refer to homogeneous collection of pointer i.e. collection of pointers of the same data type. The pointers are declared in array from same as other data types. For example an integer pointer array of size 50 can be declared as:
Int *ptr[50]
A pointer may also be used with more than one array declaration of same data type for an array pointer of size 50 can be used for first array of size 20 second array of size 20 and the third of 10. Here the pointer will be declared as:
Int a[20], b[20],c[10]:
Int *ptr [50] :
In above give expression, we can assign the address element of each array as:
Ptr [0]=&a[0] :
Ptr [20]=&a[0]:
Ptr [40]=&a[0] :
Below given is the program using array of pointers.
Example 3.13 To display the content of pointers using an array of pointes.
#include<stdio.h>
#include<conio.h>
Main ( )
{ Char *ptr1 [3]:
Clrscr( ) ;
Ptr [0] = "hello"!" ;
Prt[1] = "How are " ;
Ptr[2] = "you" ;
Print("%s%s",ptr[0],ptr1[1],ptr1[2] ;
Getch ( ) ;
}
The output of time above program will be
Hellos how are you
In above program an array of pointer of character type is declared and all the pointers are initialized. Then the contents of these pointers are displayed individually
