Menangani Strings

Ekstrak Strings

program Strings1; var s: String; c: Char; begin s := 'Hello'; c := s[1];

end.

Panjang Strings

program Strings2; var s: String; l: Integer; begin s := 'Hello'; l := Length(s);

end.

Mencari letak stringprogram Strings3;

var s: String; p: Integer; begin s := 'Hello world'; p := Pos('world',s);end.

=========================Sintaks Pos(x,y) dengan:X = string yang akan dicariY = string target pencarian

Menghapus Stringsprogram Strings4;

var s: String; begin s := 'Hello'; Delete(s,1,1);

end.=======================Sintaks secara umum: Delete(x,y,z) dengan:X = string akan dihapusY = posisi mulai penghapusanZ = jumlah string yang akan dihapus

Menyalin Stringsprogram Strings5;

var s, t: String; begin s := 'Hello'; t := Copy(s,1,3);

end.

======================Sintaks Copy(x,y,z) dengan:X = string yang akan disalinY = posisi mulai penyalinanz = jumlah karakter yang akan disalin

Menyisipkan Stringprogram Strings6;

var s: String; begin s := 'Hlo'; Insert('el',s,2);end.

=====================Sintaks Insert(x,y,z) dengan:X = string yang akan disisipkanY = string targetZ = posisi penyisipan

Parameter Stringprogram Strings7;

var s: String; i: Integer; begin s := ParamStr(0); i := ParamCount;end.

=====================ParamStr() akan memberikan paramater yang diberikan

kepada program sedang ParamCount memberikan jumlah parameter yang digunakan program.

var s: String; i: Integer; begin i := 123; Str(i,s);end.

================Str() konversi integer ke

string

program Convert2; var s: String; i: Integer; e: Integer; begin s := '123'; Val(s,i,e);end.

=====================Val() konversi string ke

integer
