Consider the code in Table 11.5, which is susceptible to a linearization attack. Suppose that we modify the program as follows:

Note that we are using the library function stremp to compare the input string to the actual serial number.

a. Is this version of the program immune to a linearization attack? Why or why not?

b. How is stremp implemented? That is, how does it determine whether the two strings are identical or not?
