Where to put Auth code here?

This is Blynk Blynk example from scetch builder for Raspberry…Where i put my Auth code here?

#define BLYNK_PRINT stdout

 #include <BlynkApiWiringPi.h>
 #include <BlynkApiLinux.h>
#include <BlynkSocket.h>
#include <BlynkOptionsParser.h>

static BlynkTransportSocket _blynkTransport;
BlynkSocket Blynk(_blynkTransport);
#include <BlynkWidgets.h>

void setup()

void loop()
  // You can inject your own code or combine it with other sketches.
  // Check other examples on how to communicate with Blynk. Remember
  // to avoid delay() function!

int main(int argc, char* argv[])
  const char *auth, *serv;
  uint16_t port;
  parse_options(argc, argv, auth, serv, port);

  Blynk.begin(auth, serv, port);

  while(true) {

  return 0;

In the declarations area above setup()

char auth[] = "AUTH";
