C++ can somebody help me create the main for this header file??

Themain()routine first calls the routineinit_vals()and initializescnt to 0, and then calls theprint_list()to print out the names of people in circle. After that it locates the M^th person in the list, and using the member functionerase(),it removes that person from the list, and by calling theprint_list()prints out the current contents of the list. This process continues (in a loop) until only one person remains in the list.

o Ifi(with initial value 0) indicates the position of a person inlist L, then the statement:j = (i + (M 1))%L.size()returns the position of the M^th person from the positioni.

o Since the argument to theerase()function is an iterator, you can convert the index valuejto an iterator by theadvance(p, j)function, wherep = L.begin().

To store the names in an empty list, first change the size of the list to N, and then use thegenerate()function in the STL. The last argument to this function is the function objectSEQ(N), which is defined in the header filejosephus.h.
