program exPointers; const MAX = 3; var arr: array [1..MAX] of integer = (10, 100, 200); i: integer; iptr: ^integer; y: ^word; begin i:=1; (* let us have array address in pointer *) iptr := @arr[1]; while (iptr
program exPointers; const MAX = 3; type iptr = ^integer; var arr: array [1..MAX] of integer = (10, 100, 200); i: integer; parray: array[1..MAX] of iptr; begin (* let us assign the addresses to parray *) for i:= 1 to MAX do parray[i] := @arr[i]; (* let us print the values using the pointer array *) for i:=1 to MAX do writeln(' Value of arr[', i, '] = ' , parray[i]^ ); end. You can also use an array of pointers to string variables to store a list of strings as follows: program exPointers; const MAX = 4; type sptr = ^ string; var i: integer; names: array [1..4] of string = ('Zara Ali', 'Hina Ali', 'Nuha Ali','Sara Ali') ; parray: array[1..MAX] of sptr; begin for i := 1 to MAX do parray[i] := @names[i]; for i:= 1 to MAX do writeln('Value of names[', i, '] = ' , parray[i]^ ); end. When the above code is compiled and executed, it produces the following result: Value of names[1] = Zara Ali Value of names[2] = Hina Ali Value of names[3] = Nuha Ali Value of names[4] = Sara Ali TUTORIALS POINT Simply Easy Learning Page 97
