I''ve got a question about function declaration (and implementation). Sometimes I''ll see a function declaration such as: void function(vector* v); and sometimes I''ll see a function declaration such as: void function(vector& v); What is the difference between the two declarations... And which should you use???

void function(vector* v); - this is a pointer
void function(vector& v); - this is a Reference

A reference is like a dereferenced pointer, you should use the reference if you want to point directly to the value stored in that part of the memory and use pointers if you want to see the memory address.

thanks
