I want to input this #011* over de serial to send using VirtualWire.h library on Rf communication.
This example i only send number:

while (Serial.available() > 0) {
    int x = Serial.parseInt();
    Serial.println(x);
    for(i=2;i>=0;i--){
      buf1[i]= x % 10;
          x /= 10;
        }
    vw_send((uint8_t *)buf1, strlen(buf1));
  }

But i want to send #011* to the receiver.Anyone help me?

Why don't you just put the string in the buffer and send it?
Am I missing something (apart from, the rest of the code)?

How is declared buf1 ?
You send buf1 ?

But in buf1 every elements are not a numerical character "011" => '0' , '1' , '1' but 0, 1 and 1 real number !!!

To send also '#' and '*' you need to declare buf1 with 2 other elements, first will be

buf[0]='#';

and last will be

buf[4]='*';

all before send

for cicle modified starting 3 to 1 but add to formula '0' to x % 10

for(i=3;i>=1;i--)
{ buf1[i]= '0' + x % 10;
   x /= 10;
}

EDIT: sorry for missing tags. Two moderator's messages for the same mistake?

And that, ladies and gentlemen, is why we ask you to please use CODE TAGS.

I declare buf[0]=’#’ and buf[4]=’*’.And put 011 over the Serial?

That was a hint.

Iam using VirtualWire.h.I have one transmitter and receiver.
I want to send #111* and the receive this sequence.
Example receive code:

#include <VirtualWire.h>

int led=13;
void setup()
{
 vw_setup(2000);
 vw_set_rx_pin(2);
 vw_rx_start();
}

void loop(){

uint8_t buf[VW_MAX_MESSAGE_LEN];
  uint8_t buflen = VW_MAX_MESSAGE_LEN;

if(vw_get_message(buf, &buflen)) // non-blocking I/O
  {
    if(buf[0]=='#'&&buf[4]=='*'){
      digitalWrite(led,HIGH);
      

   }
}
