Here is my program: ```
#include <iostream>
#include <string>
using std::string;
#include <fstream>
using namespace std;

enum State{
CODE,
IN_CHAR,
STRONG_CHAR,
IN_STRING,
STRONG_STRING,
POTENTIAL_COMMENT,
SINGLE_LINE_COMMENT,
STRONG_SINGLE_LINE_COMMENT,
MULTI_LINE_COMMENT,
MAYBE_END_OF_COMMENT
};

# 

void UNCOMMENT(const string& inputFileName, const string& outputFileName){
    ifstream inputFile(inputFileName);
    ofstream outputFile(outputFileName);

    State s = CODE;
    char c;

    while(inputFile.get(c)){
        switch(s){
            case CODE:
                if(c == '''){
                    s = IN_CHAR;
                    outputFile << c;
                }else if ( c == '/'){
                    s = POTENTIAL_COMMENT;
                }else if (c == '"'){
                    s = IN_STRING;
                    outputFile << c;
