  2. Today Topic: • Understanding using of array • Array Partice

  3. Understanding using of array • An arrayis a series or list of variables in computer memory, all of which have the same name but are differentiated with special numbers called subscripts • When you declare an array, you declare a programming structure that contains multiple elements, each of which has the same name and the same data type • You often can use a variable as a subscript to an array, replacing multiple nested decisions

  4. Understanding using of array • You can declare and initialize all of the elements in an array using a single statement that provides a type, a name, and a quantity of elements for the array • You can load an array from a file • In parallel arrays, each element in one array is associated with the element in the same relative position in the other array

  5. Array Sample • Create a psecudo code for this application: n(max. 10) = 45231 12345

  6. Array Sample START CHAR Alpha[10], Temp INTEGER I, J READ “n(Max. 10) : “, Alpha FOR I = 1 TO LEN(Alpha) DO BEGIN FOR J = I + 1 TO LEN(Alpha) DO BEGIN IF (Alpha[I] > Alpha[J]) THEN BEGIN Temp = Alpha[I] Alpha[I] = Alpha[J] Alpha[J] = Temp END END END PRINT Alpha END

  7. Array Sample • Several string basic function: • LEN(VAR) : INTEGER Ex: LEN(Name) • LEFT(VAR, nText): STRING Ex: LEFT(Name, 3) • RIGHT(VAR, nText): STRING Ex: Right(Name, 2) • MID(VAR, cText, nText): STRING Ex: MID(Name, 2, 3)

  8. Array Sample • Create a psecudo code for this application: Data(Max. 10) = 2 Name-1 : Budi Score : 75 Status : Pass Name-2 : Charles Score : 50 Status : Fail

  9. Array Sample START STRING Name[10] INTEGER Score[10], Data READ “Data(Max. 10) : “, Data FOR I = 1 TO Data DO BEGIN READ “Name : “, Name[I] READ “Score : “. Score[I] IF (Score[I] >= 60) PRINT “STATUS : PASS” ELSE PRINT “STATUS : FAIL” END END

  10. Array Partice • Create a psecudo code for this application: n (max. 5) = 3 <- User Input 4 5 8 7 2 3 = 4 5 8 7 2 3 = 2 3 4 5 7 8

  11. Array Partice • Create a psecudo code for this application: n (max. 5) = 3 <- User Input 4 2 5 8 3 4 7 2 3 5 7 8 = 4 5 8 7 2 3 = 2 3 4 5 7 8

  12. Array Partice • Create a psecudo code for this application: Text(Max. 10 Char) = BUDI <- User Input BUDI IBUD UDIB BUDI DIBU
