# gRPC in 3 minutes (C++)

## Installation

To install gRPC on your system, follow the instructions to build from source
[here](../../INSTALL.md). This also installs the protocol buffer compiler
`protoc` (if you don't have it already), and the C++ gRPC plugin for `protoc`.

## Hello C++ gRPC!

Here's how to build and run the C++ implementation of the [Hello
World](../protos/helloworld.proto) example used in [Getting started](..).

### Client and server implementations

The client implementation is at [greeter_client.cc](helloworld/greeter_client.cc).

The server implementation is at [greeter_server.cc](helloworld/greeter_server.cc).

### Try it!
Build client and server:

```sh
$ make
```

Run the server, which will listen on port 50051:

```sh
$ ./greeter_server
```

Run the client (in a different terminal):

```sh
$ ./greeter_client
```

If things go smoothly, you will see the "Greeter received: Hello world" in the
client side output.
