Example code from Linguist:

package tutorial;

option java_package = "com.example.tutorial";
option java_outer_classname = "AddressBookProtos";

message Person {
  required string name = 1;
  required int32 id = 2;
  optional string email = 3;

  enum PhoneType {
    MOBILE = 0;
    HOME = 1;
    WORK = 2;
  }

  message PhoneNumber {
    required string number = 1;
    optional PhoneType type = 2 [default = HOME];
  }

  repeated PhoneNumber phone = 4;
}

message AddressBook {
  repeated Person person = 1;
}

Example code from Wikipedia:

// polyline.cpp
#include "polyline.pb.h"  // generated by calling "protoc polyline.proto"

Line* createNewLine(const std::string& name) {
  // create a line from (10, 20) to (30, 40)
  Line* line = new Line;
  line->mutable_start()->set_x(10);
  line->mutable_start()->set_y(20);
  line->mutable_end()->set_x(30);
  line->mutable_end()->set_y(40);
  line->set_label(name);
  return line;
}

Polyline* createNewPolyline() {
  // create a polyline with points at (10,10) and (20,20)
  Polyline* polyline = new Polyline;
  Point* point1 = polyline->add_point();
  point1->set_x(10);
  point1->set_y(10);
  Point* point2 = polyline->add_point();
  point2->set_x(20);
  point2->set_y(20);
  return polyline;
}
