error: passing `const Weight' as `this' argument of `float
Weight::wgt()' discards qualifiers
seems to be some sort of standard error format that I'm not understanding.
I have code that looks like this
header file
class Weight{
public:
Weight();
explicit Weight(float wgt);
Weight(float wgt, const string &unit);
Weight(string);
float operator=(const float w );
Weight& operator=(const Weight&);
//doesn't work - assignment needs a single argument
//float operator=(const float wgt, const string &unit);
inline float wgt(){ return wgt_; };
float wgt(const float weight);
float wgt(const float weight, const string &unit);
float wgt(const string &descr);
definition or class file
Weight& Weight::operator=(const Weight &fweight)
{
//No choice but to hope it is in kilograms
unit_ = "kg";
wgt_ = fweight.wgt();
return this;
}
it all looks legal to me.

You must be a stupid engineer then, because politcs and technology have been attached at the hip since the 1st dynasty in Ancient Egypt. I guess you missed that one."
