Invlude all the steps and explanation please.

Read and understand the sample batch files posted here.

Copy them as save it in your PC as files with any name but with a $.$bat extension. Then run them in windows command prompt with just the name of the file. The power program asks for input of a number and a power $($also a number$),$ calculates and outputs the power of the number.

Write a batch program to accept a number as input from the user and calculate the factorial of a number. You must continue to accept input as long as the user enters option$($y$/$n$)$ as $\text{'}$y$\text{'}$ for an input. If the user types $\text{'}$n$\text{'}$ then you can end the program. $($You can follow similar approach used in the power program$)$

Batch File $1$:

@echo off

echo "This is addition of two numbers"

set $/$p a$=$"num$1"$

set $/$p b$=$"num$2"$

set $/$a s$=$a $+$ b

echo sum $=\%$s$\%$

pause

Batch file $2$:

@echo off

echo "This is finding the power of a number"

:loop

set $/$p a$=$"num$1"$

set $/$p pow$=$"power $"$

if $\%$pow$\%$ LSS $0$ goto step$1$

if $\%$pow$\%==0$ goto step$2$

set $/$a result$=1$

set $/$a power$=0$

:loop$1$

set $/$a result$=\%$result$\%*\%$a$\%$

set $/$a power$=\%$power$\%+1$

if $\%$power$\%$ GEQ $\%$pow$\%$ goto step$3$

goto loop$1$

:step$3$

echo "power $\%$pow$\%$ of the number $\%$a$\%$ is $\%$result$\%$

goto step$4$

:step$2$

echo "power $\%$pow$\%$ of the number $\%$a$\%$ is $1"$

goto step$4$

:step$1$

echo "invalid entry"

:step$4$

echo $"$do you want to enter another number $?"$

set $/$p option$="$y$/$n $"$

if $\%$option$\%==$ y goto loop

pause
