narrowing conversion of long long int to long unsigned int inside {} [-Wnarrowing]

问题

now the newer error "narrowing conversion of long long int to long unsigned int inside {} [-Wnarrowing]"

the source code relative to it:

// Implements the joint conditional cummulative density functions for CP-nets
// For node j in the lexicographic topological sort as defined by the dag code:
// the table gives P( s, t | n, c, j ).
// The number of rows in each table is the triangular number of min(c, j).

I think error got from and every where there is unsigned long int, but i don't know how fix it,

const unsigned long int factorial[17] = {1, 1, 2, 6, 24, 120, 720, 5040, 40320, 362880, 3628800, 39916800, 479001600, 6227020800, 87178291200, 1307674368000, 20922789888000};

so can help me fix it? thank you
