#
## I4VEC_SUM_VEC does a pairwise sum of two I4VEC's.
#
#  Discussion:
#
#    An I4VEC is a vector of I4's.
#
#  Example:
#
#    Input:
#
#      A = ( 1, 2, 3, 4 )
#      B = ( 5, 6, 7, 8 )
#
#    Output:
#
#      C = ( 6, 8, 10, 12 )

#
#  Parameters:
#
#    Input, integer N, the number of entries in the vector.
#
#    Input, integer A(N), B(N), the vectors to be summed.
#
#    Output, integer C(N), the pairwise sum of A and B.
