I get the following error Invalid arguments ' Candidates are: char * getName() ' for the above instruction.What am I missing?

char* Medicine::getName() 
{
    return this->name;
}

name is of declared as char name[50]; andm is const Medicine& m

Please note that if the member variable is const, only const member function can access this. Same for static, i.e if the member variable is static only a static member can access that.

If m is const, then only const methods can be called on it. Maybe you can change your method to

const char* Medicine::getName() const;

and use it like this:

const char* n=m.getName();

Although you might consider using an std::string data member instead of an array of char.
