Line 18 uses vector
member function size to obtain the size (i.e., the number of elements) of integers1
. Line 20 passes integers1
to function outputVector
(lines 96–102), which uses a range-based for
statement to obtain the value in each element of the vector
for output. As with class template array
, you can also do this using a counter-controlled loop and the subscript ([]
) operator. Lines 23 and 25 perform the same tasks for integers2
.
