I am attempting to load a structure using an istream. Is there a way an istream can read/ignore specific characters or can I enforce this somehow? This is currently what I have:

struct MyStruct
{
    unsigned int  identifier;
    float         value;
    float         bob1;    
    float         bob2;    

    std::istream& operator>>(std::istream& in, MyStruct& s)
    {
        in >> identifier >> value
           // Can I do this?
           >> '[' >> bob1 >> ',' >> bob2 >> ']';
    };
};

You just want to ignore the brackets? What do you want to do if the brackets aren't there? – stark Dec 20 '19 at 17:04
Right now I don't care if I bomb. – jiveturkey Dec 20 '19 at 17:06
@NathanOliver thanks for the reference – jiveturkey Dec 20 '19 at 17:06
Read into char variables na1 and na2 and ignore them. – stark Dec 20 '19 at 17:07
Yeah, that makes good sense as well but I want them to be specifically those characters and not just any character. – jiveturkey Dec 20 '19 at 17:07
Which is why I asked what to do if they aren't. – stark Dec 20 '19 at 17:09
