I tried to define an overloader for the operator <<. My source
code is great except the stupid compiler doesn't get it. std: stream& Particle:perator<< (Particle& part) {std: stream* ost = NULL;(*ost) << "diffusion particle"; return (*ost); } The error message is error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'Particle' (or there is no acceptable conversion) What did i do unsmartly? -- Vänligen Kerstin Viltersten (The Cool Giraffe) |
