std::ostream_iterator::operator=
From cppreference.com
< cpp | iterator | ostream iterator
ostream_iterator& operator=( const T& value );

||
Inserts value
into the associated stream, then inserts the delimiter, if one was specified at construction time.
If out_stream
is the private member pointer to the associated std::basic_ostream and delim
is the pointer to the first character in the delimiter, the effect is equivalent to
*out_stream << value;
if(delim != 0)
*out_stream << delim;
return *this;

[edit] Return value
*this
[edit] Notes
T
can be any class with a user-defined operator<<
[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; }
Output:
1, 2, 3, 3.14
