I dont know what I am doing wrong... it keeps saying that it is skipping things when i run the debug... I am working on creating classes and then impliminting them in the main

here is the code I have so far...

int main$()$

$\{$

int choice $=0$;

string input;

int offsetInput;

string encoded;

string decoded;

do $\{$

cout $<<"[1]$ Set offset

$[2]$ Encode a message

$[3]$Decode a message

$[4]$ Exit

$"<<$ endl;

cin $>>$ choice;

switch $($choice$)\{$

case $1$:

cout $<<$ "What offset? $"$;

cin $>>$ offsetInput;

TextCodec$($offsetInput$)$;

break;

case $2$:

cout $<<$ "What message? $"$;

getline$($cin$,$ input$)$;

TextCodec codec;

encoded $=$ codec.Encode$($input$)$;

cout $<<$ encoded $<<$ endl;

break;

case $3$:

cout $<<$ "What message? $"$;

cin.ignore$()$;

getline$($cin$,$ input$)$;

TextCodec codec;

decoded $=$ codec.Decode$($input$)$;

cout $<<$ decoded $<<$ endl;

break;

case $4$:

cout $<<$ "Thanks for playing";

break;

$\}$

$\}$ while $($choice$!=4)$;

$\}$;

class TextCodec $\{$

$//$attributes

short int offset;

public:

$//$default constructor

TextCodec$()\{$

SetOffset$(0)$;

$\}$

$//$overload constructor

TextCodec$($short int offset$)\{$

SetOffset$($offset$)$;

$\}$

void SetOffset$($short int offset$)\{$

this$->$offset $=$ offset;

$\}$

$//$encode method

string Encode$($string message$)\{$

std::string result $=$ message;

for $($int i $=0$; i $<$ message.length$()$; i$++)$

$\{$

result$[$i$]=($char$)($result$[$i$]+$ offset$)$;

$\}$

return result;

$\}$

$//$decode method

string Decode$($string message$)\{$

std::string result $=$ message;

for $($int i $=0$; i $<$ message.length$()$; i$++)$

$\{$

result$[$i$]=($char$)($result$[$i$]-$ offset$)$;

$\}$

return result;

$\}$

$\}$;
