Question

USING WINDOWS BATCH SCRIPTING

topic: Implement division by 0, with error trapping, using if and sumilating while loops -

Using the NOTEPAD editor, append to the *.bat file, all the commands needed so that when you execute your bat file, it will produce the following:

a) Append your name and class name and section.

b) Using two variables: FirstNumber and SecondNumber,

c) Ask the user to enter the first number.

d) Ask the user to enter the second number.

e) If the user enters the value 22 for the first or the second number, you must exit the loop immediately, and terminate this section ONLY.

f) If the second number is ZERO inform the user that you CAN NOT divide by ZERO, and ask for a correct second number.

g) If the second number is NOT a zero, do the division, display all numbers of this computation using labels, example: 4 divided by 1 = 4

Answer 1

Code:

divide.bat:

@echo off
::this will prevent each line to output on cmd

::take 1st number into FirstNumber variable and /p allows you take user input here
set /p FirstNumber=Enter 1st number :

::as required if FirstNumber is se to 22 it will terminate using exit /b and 0 indicates program executed successfully
if %FirstNumber%==22 exit /B 0

::while loop start's here hence lable
:while
::take 2nd number into SecondNumber variable and /p allows you take user input here
set /p SecondNumber=Enter 2nd number :

::as required if FirstNumber is se to 22 it will terminate using exit /b and 0 indicates program executed successfully
if %SecondNumber%==22 exit /B 0

::if SecondNumber is equal to 0 then prompt and go to while lable above
if %SecondNumber%==0 (
   echo You cannot divide by zero
   goto :while
)

::perform division and store in ans variable
set /A ans=%FirstNumber%/%SecondNumber%

::Output final ans
echo %FirstNumber% divided by %SecondNumber% = %ans%
