need help to pass values to array in for loop

[A.kalyani]

can anyone please help me?

i have two decimal arrays l(15),r(15)
loop has to repeat for 16 times.l(15) , r(15) is the result i have to get.i wrote function F and it is executing perfectly.but atlast r(15) and l(15) is showing as system.decimal[].if i tested with ordinary variable other than array variable.its giving result.values are not passing to arrray

For b As Integer = 0 To 15
t = Decimal.Parse(r(b).ToString)
dim ta as decimal=Decimal.Parse(((l(b) And F(r(b)))).ToString)
'above line is working perfectly and its showing result.
r(b + 1) = Decimal.Parse(((l(b) And F(r(b)))).ToString)
'above line is not working.its giving result as system.deciamal[]
l(b + 1) = Decimal.Parse(t.ToString)
Next

First I don't know what F is returning. Is it a decimal?
Next you are converting a decimal to a string and then converting it back to a decimal. Big waste of resources. If F is returning a decimal then remove all Decimal.Parse.

Dim r(15), l(15) As Decimal
        Dim t As Decimal

        For b As Integer = 0 To 15
            t = r(b)
            Dim ta As Decimal = l(b) And F(r(b))
            r(b + 1) = l(b) And F(r(b))
            l(b + 1) = t
        Next

You are going to run into problems when b gets to 15 and try to set r(b+1) which is 16, You will get an index out of range error.
