@mainpage Cloud BigQuery C++ Client Library

The Cloud BigQuery C++ Client library offers types and functions to use Cloud

BigQuery from C++ applications.

While this library is **GA**, please note Google Cloud C++ client libraries do **not** follow [Semantic Versioning](https://semver.org/).

@tableofcontents{HTML:2}

## Quickstart

The following shows the code that you'll run in the

`google/cloud/bigquery/quickstart/` directory, which should give you a taste of

the Cloud BigQuery C++ client library API.

## Main classes

<!-- inject-client-list-start -->

This library offers multiple `*Client` classes, which are listed below. Each one

of these classes exposes all the RPCs for a service as member functions of the

class. This library groups multiple services because they are part of the same

product or are often used together. A typical example may be the administrative

and data plane operations for a single product.

The library also has other classes that provide helpers, configuration

parameters, and infrastructure to mock the `*Client` classes when testing your

application.
