Hi Afif, adc_init and adc_sample are functions of the RIOT peripheral API [1] and they are implemented by each platform (that has an ADC). Personally, I'd always recommend to use these directly (see [2] for an example).
However, if you really want to use the Arduino API I'd suggest, as a first step, add the analorRead calls to examples/arduino_hello-world and see if this works for arduino-due.
