# 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 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;

### [edit] Parameters

value | - | the object to insert

### [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
