std::ostream_iterator<T,CharT,Traits>::operator=

Edit page
  1. Copy assignment operator. Assigns the contents of other

# Declarations

ostream_iterator& operator=( const ostream_iterator& );

ostream_iterator& operator=( const T& value );

# Parameters

# Return value

*this

# 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.

# Example

#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';
}
