Hi guys, i'm writing a simple code which is about polynomials using link lists in C#. the problem i have is that whenever it creates a new struct (node) in the for loop it gives it the same address as the previous node was given. so how do i fix it ? here is my struct :

struct poly { public int coef; public int pow; public poly* link;} ;

and here is the where the problem occurs:

for (; i < this.textBox1.Text.Length; i++)
            {
                q = new poly();
                ......
                p->link = &q;
            }

&q remains unchanged !
