constexpr basic_string_view
substr(size_type pos = 0, size_type count = npos ) const ; |
||
Returns a view of the substring [pos, pos + rcount)
, where rcount
is the smaller of count
and size() - pos
Parameters
pos | - | position of the first character |
count | - | requested length |
Return value
View of the substring [pos, pos + rcount)
.
Exceptions
std::out_of_range if pos > size()
Complexity
Constant.
