C++ Input is a header library to perform formatted input in C++, licensed under the LGPL.

For example, a float and an unsigned integer can be read:

float f;
unsigned u;

// Read a float, then an integer
cppinput::input(cin, "{} {}", f, u); 

User defined types can be input as long as they provide an input stream operator.

class Date {
public:

    friend istream &operator >>(istream &in, Date &d) 
    {   
        if(!cppinput::input(in, "{}-{}-{}", d.year, d.month, d.day))
            in.setstate(std::ios::failbit);
        return in; 
    }   

    unsigned year, month, day;
};


Date d;
cppinput::input(cin, "Date: {}", d);
