Which of the following is not a difference between hex and setbase? setbase is a parameterized stream manipulator and hex is not. setbase is provided by a different header file than hex. setbase(16) and hex have different effects on stream output. setbase takes an argument but hex does not.

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
