Hello, I$\text{'}$m in a c$++$ coding class, so far we have learned functions, loops and basic variables. Could someone show me how to code this in C$++?$ Now that you know how to shift characters and how to get the shift value from a keyphrase, you want to implement method $1$ and $2$ so that

you can use these methods before your next class.

Write a function named getLayer$1$MessageEncryption$()$ that encrypts a message based on the user selected encryption method.

The encryption method choices are as follow:

Shift right by $13$

Shift right by mixed keys

See the overview section for description, equation and examples for the two encryption methods.

Function:

getLayer$1$MessageEncryption$($string$,$

int, string, string$)$

Purpose:

Parameters:

Return Value:

Error Handling$/$Boundary Conditions:

string getLayer$1$MessageEncryption$($string message, int method$\_$choice, string key$1,$

The function should encrypt the message based on the user selected encryption method. It st

anything.

string message $-$ The message to be encrypted.

int method$\_$choice $-$ The encryption method.

string key$1-$ The first key.

string key$2-$ The second key.

If successful, return the encrypted message.

If message is an empty string, then return the empty string.

If method$\_$choice is outside range$[1,2],$ then return message $.$

If method$\_$choice is equal to $2$ and key$1$ or key $2$ is an empty string, then return messag
