Hi, can somebody help me with this code, i tried to run it with F11 to see the flow but i just cant understand how does it changed.,

Sub main
try
  dim cls as new mysample class
  dim var1,var2,var3,result as decimal
  dim counter as integer
  var1=convert.todecimal(inputbox("enter a number(0,1 or 2)"))
  for counter=0 to 1
    myarray(counter)=convert.todecimal(inputbox("Enter another number"))
  next
 
  var2=mayarray(0)
  cls.s=myarray(1)
  result=cls.compute(var1,var2)
  msgbox(result)
catch ex as exceptiopn
  msgbox(ex.msg)
end try
end sub
 
PUblic class mysampleclass
private x as integer
property s() as decimal
get
  return x
end get
set(byval value as decimal)
  x=value
end set 
end property
 
 
 
function compute(byval a as decimal, byval b as decimal) as decimal
 
select case a
case0
  return(s+b)
case1
  return (s+b+b)
case2
  return(s+s+b)
end select 
end function
end class

q:

why after doing (byval a as decimal, byval b as decimal) as decimal?
we type as decimal after we have declare that a and b as deciaml

why everytime i input 1 firts ,2, , 2= 6
whats the possible reason thanks....

..

a and b are the parameters which are accepted by this function. The As Decimal at the end indicates the value type that the function returns.

why everytime i input 1 firts ,2, , 2= 6
whats the possible reason thanks....

Sorry, didn't understand that question - could you try to be more clear?

[when i run the program
it will ask me to input a number from the choices either 0,1 or 2

if i input 1,then i will ask me again to input another number, and i choose 2, it will direct me again to inputbox teling me to input another number, and i chose to input 2

then i will generate a Result message 6

the question is, how did it come to result 6,whereas i only input the total of 5
which are 1,2,2 respectively?

can you solve it for me pls.. i just cant figure it out... thanks again maa'm

If you trace through the code step by step, you will see that what is being executed here is return (s+b+b). This comes to 6 (2+2+2).

Yeah, but how about 1,1,2 then result is 5, thanks again....

Trace the code through, step by step. It's more important for you to understand it than me.

I think it's critically important, as a programmer, to be able to follow and understand program code. Otherwise how will you ever know what you're writing? Just keep in mind that although a program may look overwhelming when viewed as a whole, the computer is completely dumb and only does one simple thing at a time. You just need to understand the result of each individual statement, to follow the execution.

Ok, thanks, but im not taking up programming, im taking up System engineering. so im quite dumb with this, thanks again maa'm....
