Write a function bool ok(int q[], int c) for the "eight numbers in a cross" problem. ok returns true if the configuration in q[0] through q[c] is fine according to the rules discussed in class. note that the array int a[8][5] should be local to the function (and static) since that is the only place that it is used.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
