AS computing 2011 July Batch

[Ravichandran]

Dear all,

            Welcome to AS computing class. I am Dr.Ravi your facilitator for this course. This course consists of two modules, theory and practicals. In theory we will have 12 chapters and in practicals we do have programming classes. You will sit for theory and practical exams at the end of the course, which is conducted by CIE.

All the best, keep moving, for there is always a helping hand above you to guide you.

Dr.Ravi

Dain, what is Asc(x) and Chr$(p-32) ?

[Mohamed Faiz bin Mohamed Razali]

Dain, the Chr$(p-32) rite , what does it mean?

[Ahmad Syahmi Irfan]

Thanks guys, em why some coding doesn't print when we run that program?can anyone tell me,

Dain, why chr$ ?

Question 5 ( Change a small letter to a capital letter)

 

Dim p As Integer

x = InputBox("Enter a small letter")

p = Asc(x)

Form1.Print Chr$(p - 32): MsgBox "Done": End

 

This one is surprisingly short... :/

dain, do we have to put the "$" after the "chr" ? i deleted it and it still works...

Today's Lesson:

Tracing The Output!!!

Dim a(5) As Integer

10 I = I + 1

b = InputBox("Enter Value")

a(I) = Val(b)

If I = 5 Then GoTo 20

GoTo 10

20 P = 1

BIG = a(P)

30 P = P + 1

If BIG < a(P) Then BIG = a(P)

If P = 5 Then GoTo 40

GoTo 30

40 Print BIG

MsgBox ("Biggest Value")

 

To Trace the Output, better to make 6 columns in a table as such:

 

P	BIG	a(P)	If BIG < a(P)	BIG=a(P)	Output
1	37	a(1)
2	37	a(2)	37<74 True	74
3	74	a(3)	74<54 False	74
4	74	a(4)	74<48 False	74
5	74	a(5)	74<18 False	74	74

 

 

 

this makes a clearer view of what the computer is working on, and hopefully we get the right output XD

Assignment- Syahmi

[Dain Razali]

Ok I'll try my best to explain to u guys..

 

Asc is a code used to change a character(eg. a, B, C, d etc.) into its ACSII code. For example...if u type Form1.print Asc("A") in VB, u will get the result 65, which is the ASCII code of capital A...

 

Chr$ on the other hand is an inverse form of Asc where it is used to change an ASCII code to a character. For example....typing Form.print(65) in VB will give u the character 'A' as the result. 

 

Therefore in the program that i wrote, i used p=Asc(x), where x is a small letter and hence p will be the ASCII code of the character entered. Then i gave a print statement to print Chr$(p-32) since the 'ASCII code of a capital letter=ASCII code of small letter - 32'.

Since the code Chr$ will change the ASCII code into a character, hence the capital letter of the entered character will be printed out. 

 

Thats bout it. Hope u guys understand what i'm trying to say. :)

[Dain Razali]

I have no idea what the $ is for Cho...U have to ask Dr. Ravi bout that....maybe it's something to do with a string variable of some sort :/
