Simple Batch File Programming

Write a batch file that would input a users choice based on the table below:

Choice	Input the following	Compute & Output
“C” for Circle	Radius of a Circle	Area = pr2
“S” for Square	Side of Square	Area = s2
“R” for Rectangle	Length & Width of a Rectangle	Area = lw
“T” for Triangle	Base & Height of a Triangle	Area = 1/2 bh

Code:
@echo off
:top
echo Select a Letter Below:
echo c for Circle
echo s for Square
echo r for Rectangle
echo t for Triangle
echo -------------------------
set /p input=Input:
if %input%==c (
goto :c
) else if %input%==s (
goto :s
) else if %input%==r (
goto :r
) else if %input%==t (
goto :t
) else (
echo Invalid Input. Please select again.
pause
cls
goto :top
)

:c
set /p radius=Radius:
set pi=314/100
set /a area=%radius%*%radius%*%pi%
echo Area = %area%
pause
cls
goto :top

:s
set /p side=Side:
set /a area=%side%*%side%
echo Area = %area%
pause
cls
goto :top

:r
set /p length=Length:
set /p width=Width:
set /a area=%length%*%width%
echo Area: %area%
pause
cls
goto :top

:t
set /p base=Base:
set /p height=Height:
set /a area=%base%*%height%
set /a area=%area%/2
echo Area: %area%
pause
cls
goto :top

Write a batch file that would input a course code and output its equivalent course;

Input => Course Code                        Output => Course

                        A or a              “Accounting”

                        B or b              “Banking and Finance”

                        C or c              “Computer Science”

                        D or d              “Dentistry”

                        E or e               “Engineering”

                        else                  “Invalid Course Code”

 Code:
@echo off
:top
set /p course=Course Code:
IF %course%==a (
echo "Accounting"
pause
cls
goto :top
) ELSE IF %course%==A (
echo "Accounting"
pause
cls
goto :top
) ELSE IF %course%==b (
echo "Banking and Finance"
pause
cls
goto :top
) ELSE IF %course%==B (
echo "Banking and Finance"
pause
cls
goto :top
) ELSE IF %course%==c (
echo "Computer Science
pause
cls
goto :top
) ELSE IF %course%==C (
echo "Computer Science
pause
cls
goto :top
) ELSE IF %course%==d (
echo "Dentistry"
pause
cls
goto :top
) ELSE IF %course%==D (
echo "Dentistry"
pause
cls
goto :top
) ELSE IF %course%==e (
echo "Engineering"
pause
cls
goto :top
) ELSE IF %course%==E (
echo "Engineering"
pause
cls
goto :top
) ELSE (
echo "Invalid Course Code"
pause
cls
goto :top
)

Write a batch file that would input a year code and output year level.

Input => Year Code               Output => Year Level

                        1          “First Year” next line “Freshmen”

2          “Second Year” next line “Sophomore”

3          “Third Year” next line “Junior”

4          “Fourth Year” next line “Senior”

Code:
@echo off
:top
set /p year=Year Code:
echo Year Level:
IF %year%==1 (
echo First Year
echo "Freshmen"
pause
cls
goto :top
) ELSE IF %year%==2 (
echo Second Year
echo "Sophomore"
pause
cls
goto :top
) ELSE IF %year%==3 (
echo Third Year
echo "Junior"
pause
cls
goto :top
) ELSE IF %year%==4 (
echo Fourth Year
echo "Senior"
pause
cls
goto :top
) ELSE (
echo "Invalid Year Code"
pause
cls
goto :top
)
