At this time we have a task for you to do$.$ You are to write several

functions that do binary math on character strings of $\text{'}$T$\text{'}$s and $\text{'}$F$\text{'}$s$.$ The

functions you will fill in are: WRITE USING THE LANGUAGE C

#include

#include

#include "binarymath. $h"$

$/**$

Negate a BINARY$\_$SIZE binary number expressed as a character string

Cparam number The number we are passed

ereturns negated version of the number

$**\frac{*}{?}$

char $*$negate$($const char $*$number$)$

$[$

$\}$

return number;

$/**$

Add two BINARY$\_$SIZE binary numbers expressed as

a character string.

Eparam a First number to add

Cparan b Second number to add

ereturn $a+b$

$*\frac{*}{?}$

char $*$add$($const char $*$a$,$ const char $*$b$)$

$[$

return a;

$\}$

$/**$kt$.$

Subtract two BINARY$\_$SIZE binary numbers expressed as

a character string.

Cparam a First number

Cparam b Second number

ereturn a $-$ b

$**\frac{*}{?}$

char $*$sub$($const char $*$a$,$ const char $*$b$)$

f

$\}$

return $a$;

$1****$

Multiply two BINARY$\_$SIZE binary numbers expressed as

a character string.

Cparam a First number

Ceparam b Second number

erreturn $a**b$

$*\frac{*}{?}$

char ${?}^{**}$ mul $($const char ${?}^{**}a,$ const char $\{$:${?}^{**}b)$

$[$

$\}$

return $a$;

The file binarymath.h includes the constant BINARY$\_$SIZE:

$///$ The size of the binary numbers to use

#define BINARY$\_$SIZE $100$

You can use this value in expressions just like any other number:

Create a circuit for $2-$to$-4$ demultiplexer in Cirsim. Name the inputs S$0,$

$S1,$ and I. Name the outputs $00,01,02,$ and $03.$ They should match the

same values in the characteristics table table.
