QBasic program to know the output of program using dry run table- to find the sum of numbers between 1 and 9 using function procedure

declare function find()

Print find

End

Function find ()

    For n = 1 To 9 Step 2

        Let s = s + n

    Next n

    find = s

End Function

Dry run table

N=1 to 9 step 2	S=s+n	find
N=1;true	S=0+1=1
N=3;true	S=1+3=4
N=5;true	S=4+5=9
N=7;true	S=9+7=16
N=9;true	S=s+N=16+9=25
N=11;false		Find=s=25

output
