QBasic program to know the output of program using dry run table- to print the characters from given string

DECLARE SUB CHEMISTRY()

Cls

Call CHEMISTRY

End

Sub CHEMISTRY ()

    Let A$ = "VIDEO"

    Let B = Len(A$)

    For I = 1 To 4

        Print Mid$(A$, I, B)

    Next I

End Sub

DRY RUN table with output is given below

A$	B=LEN(A$)=5	I= 1 TO 4	MID$(A$,I,B)
VIDEO	B=5	I=1	MID$(A$,I,B)=VIDEO
	B=5	I=2	MID$(A$,I,B)=IDEO
	B=5	I=3	MID$(A$,I,B)=DEO
	B=5	I=4	MID$(A$,I,B)=EO

output:

VIDEO

IDEO

DEO

EO

QBasic program to know the output of program using dry run table- to extract characters and print them

DECLARE FUNCTION OUTPUTT$(W$)

Cls

W$ = "CRIMES"

Print OUTPUTT$(W$)

End

Function OUTPUTT$ (W$)

    For M = Len(W$) To 1 Step -2

        M$ = M$ + Mid$(W$, M, 1)

    Next M

    OUTPUTT$ = M$

End Function

DRYRUN table for above program is given below

W$	M=6 TO 1 STEP-2	M$=M$+MID$(W$,M,1)	OUTPUTTT$
CRIMES	M=6	M$=S
	M=4	M$=S+M=SM
	M=2	M$=SM+R=SMR	SMR

Output:-

SMR
