Answer:

Both statements looking the same but actually, both are different from each other.

Statement 1 will be expanded to struct sStudentInfo * p1, p2. It means that p1 is a pointer to struct sStudentInfo but p2 is a variable of struct sStudentInfo.

In statement 2, both q1 and q2 will be a pointer to struct sStudentInfo.
