problem conversion value

Question

I have two functions that return an int16_t but I need to convert the ints to char* is for an attiny13

It would be something like this

const char* msg = "value1()"+','+"value2()"+','+"value3()"

like example

#include "TinyRF_TX.h"
void setup(){
  // transmitter default pin is pin #2. You can change it by editing Settings.h
  setupTransmitter();
}
void loop(){
const char* msg = "Hello from far away!";
//send function accepts an array of bytes as first argument
  //second argument is the length of the array
  send((byte*)msg, strlen(msg));
//make sure there's at least a TX_DELAY_MICROS delay between transmissions
  //otherwise the receiver's behavior will be undefined
  delayMicroseconds(TX_DELAY_MICROS);

You will need to build the string yourself. Probably the easiest way is using the sprintf() function which will take a bunch of arguments and convert them to a string based on formatting instructions you give it.
