Have an error dealing with the std string class

[brokenbot]

Apparently the compiler doesn't like my arguments for std::string::append()
The error is invalid conversion from char to const char*

  ImgType[i].append(Img[i].at(g));

Also I dereferenced and whatever it is called with *blah and &blah
It compiles but semantic error occurs with &blah

See the reference section re: string::append.

Instead use operator +=

ImgType[i] += Img[i].at(g);

[brokenbot]

I've tries that and ImgType[i].append(&Img[i].at(g));

Both give errors of semantic types. Reads in console aborted terminate called after throwing an instance of std::out_of_range
What(): basic_string::at

That means Img[i] is shorter than g characters.

Yeah that's what I thought. Thanks
