A random question

struct variables

       int func()
       {
           v[0].a = 10;
           cout<<v[0].a<<endl;//this is a small example of how to implement this
           //concept you might want to use a for statement rather than an if
           //statement that way it chooses the right variable. I could probably
           //help better if I knew better what your program was intended to do
       }
