Hi,

So I'm having an issue with the code that I've made for my Object Oriented Programming class. I'm trying to get through one of the challenges MyProgrammingLab 70046 to be exact. I keep getting errors:

Severity Code Description Project File Line Suppression State

I keep getting a red line under ofs in the main. I bolded the spots where I'm having the issue. Here's my code so far:

#include

#include

#include

using namespace std;

class Filter

{

private:

istream& is;

ostream& os;

public:

Filter(void) : is(cin), os(cout)

{

}

Filter(ifstream& ifs, ofstream& ofs) : is(ifs), os(ofs)

{

}

virtual char transform(char c) const = 0;

void doFilter(void)

{

char ch = '?';

while (is.peek() >-1);

{

ch = is.get();

os << transform(ch);

}

}

};

class Copy : public Filter

{

public:

Copy(void) : Filter()

{

}

Copy(ifstream& ifs, ofstream ofs) : Filter(ifs, ofs)

{

}

virtual char transform(char ch) const

{

return ch;

}

};

class Encr :public Filter

{

public:

Encr(void) : Filter()

{

}

Encr(ifstream& ifs, ofstream ofs) : Filter(ifs, ofs)

{

}

virtual char transform(char ch) const

{

if (ch >= 'A' && ch <= 'Z')

{

ch = ch - 65;

ch = ch + 13;

ch = ch % 26;

ch = ch + 65;

}

else if (ch >= 'a' && ch <= 'z')

{

ch = ch - 97;

ch = ch + 13;

ch = ch % 26;

ch = ch + 97;

}

else

{

return ch;

}

}

};

class Upper : public Filter

{

public:

Upper(void) : Filter()

{

}

Upper(ifstream& ifs, ofstream ofs) : Filter(ifs, ofs)

{

}

virtual char transform(char ch) const

{

if (ch >= 'a' && ch <= 'z')

return toupper(ch);

else

return ch;

}

};

int main(void)

{

Filter* fp;

string ifname = "input.txt";

string ofname;

ifstream ifs;

ofstream ofs;

ifs.open(ifname.c_str());

ofname = ifname + "_copy";

ofs.open(ofname.c_str());

if (ifs.is_open() && ofs.is_open())

{

fp = new Copy(ifs, ofs);

fp->doFilter();

ifs.close();

ofs.close();

delete fp;

}

ifs.open(ifname.c_str());

ofname = ifname + "_encr";

ofs.open(ofname.c_str());

if (ifs.is_open() && ofs.is_open())

{

fp = new Encr(ifs, ofs);

fp->doFilter();

ifs.close();

ofs.close();

delete fp;

}

ifs.open(ifname.c_str());

ofname = ifname + "_upper";

ofs.open(ofname.c_str());

if (ifs.is_open() && ofs.is_open())

{

fp = new Upper(ifs, ofs);

fp->doFilter();

ifs.close();

ofs.close();

delete fp;

}

return 0;

}

Any help would be greatly appreciated!
