std::ostream_iterator
Member functions
ostream_iterator::operator=
ostream_iterator& operator=( const ostream_iterator& );
(1)
ostream_iterator& operator=( const T& value );
(2)
1) Copy assignment operator. Assigns the contents of other
2) Inserts value into the associated stream, then inserts the delimiter, if one was specified at construction time.
If out_stream is a pointer to the associated std::basic_ostream and delim is the delimiter specified at the construction of this object, then the effect is equivalent to
*out_stream << value;
if (delim != 0)
*out_stream << delim;
return *this;
Contents
[edit] Parameters
value
-
the object to insert
[edit] Return value
*this
[edit] Notes
T can be any class with a user-defined operator<<.
Prior to C++20, the existence of the copy assignment operator relied on the deprecated implicit generation.
[edit] Example
Run this code
#include <iostream> #include <iterator> int main() { std::ostream_iterator <int> i1(std::cout, ", "); *i1++ = 1; // usual form, used by standard algorithms *++i1 = 2; i1 = 3; // neither * nor ++ are necessary std::ostream_iterator <double> i2(std::cout ); i2 = 3.14; std::cout << '\n'; }
Output:
1, 2, 3, 3.14
