Your country is at war and your enemies are using a secretcode to communicate with each other. You have managed to intercepta messsage that reads as follows:

:mmZ$\backslash$dxZmx$]$Zpgy

The message is obviously encrypted using the enemy's secretcode$.$ You have just learned that their encryption method is basedupon the ASCii code. Appendix $3$ shows the ASCii character set.Individual characters in a string are encoded using this system.For example, the letter $"$A$"$ is encoded using the number $65$ and $"$B$"$is encoded using the number $66.$

Your enemy's secret code takes each letter of the message andencrypts it as follows:

If$($OrigialChar $+$ Key $>126)$ then

EncryptedChar $=32+(($OriginalChar $+$Key$)-127)$

Else

EncrptedChar $=($OriginalChar Key$)$

For example, if the enemy uses Key $=10$ then the message "Hey"would be encrypted as:

Character ASCii code

$--------------------------$

H $72$

e $101$

y $121$

Encryped H $=(72+10)=82=$ R in ASCii

Encrypted e $=(101+10)=111=$ o in ASCii

Encrypted y $=32+((121+10)-127)=36=$ $ in ASCii

Consequently, "Hey" would be transmetted as $"$Ro$$".$

Write a program in C$++$ that is capable of both encryption of the secret code and decryption of the intercepted message. The ASCII codes for the unencrypted message are limited to the visible ASCII characters.

The secret key used is a number between $1$ and $100.$

$**$The code should be organized as follows:

$-$ You would need two functions; both have as inputs the original message along with the encrypted message, and the key.

void encryption $($char original $[],$ char secret $[],$ int key$)$;

void decryption $($char original $[],$ char secret $[])$;

$-$ The encryption function uses the original message and the key to populate the secret message.

$-$ The decryption function uses the secret message and a combination of all possible keys between $1$ and $100$ to decode the message. When you try the valid key, the message

will make sense. For all other keys, the message will appear gibberish.

$-$ Both functions can be called inside the main for testing purposes. Generate $2$ arrays to accommodate the original and secret messages. Keep the size of the array capped to $1000$ characters. The end of each message is designated by a null character $\backslash 0.$
