:relfileprefix: ../
:mrdocs:

Copies elements from `input` to `output`. `absl::c_copy(input, output)` is equivalent to `std::copy(std::begin(input), std::end(input), std::begin(output))`.

== Synopsis

Declared in `<absl/algorithm/container.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<
    typename InputSequence,
    typename OutputRange>
constexpr
/* implementation-defined */
c_copy(
    InputSequence const& input,
    OutputRange&& output);
----

== Description

The `output` container must be large enough to hold all elements of `input`; this function does not resize `output`.

If `std::size(input) > std::size(output)`, behavior is undefined. If `std::size(output) > std::size(input)`, only `std::size(input)` elements are copied, and `output` is not truncated.

== Return Value

This overload returns no value; the results are written into `output`.

== Parameters

| *input*
