/*Given below is a code snippet in C showing a function that finds the 
smallest of 2 numbers :

int get_smallest(int x,int y){
  int smallest;
  if(x<=y){
    goto assign_x;
    }
  smallest=y;
  goto done;
  assign_x:
      smallest=x;
  done:
      return smallest;
      
Write the complete program (to be run in Rapberry Pi Pico) where:
- The C Program should get the inputs (2 numbers) from the user and call the assembly
function
- The assembly function should compare and find the smallest number among the 2 inputs
and return the smallest one to the C program.*/
#include <stdio.h>
#include <stdlib.h>

extern "C"{
   int get_smallest(int x,int y); //2 parameters.
}

void setup() {
  Serial1.begin(9600); //initialising the serial port.
}

int main()
{
  int x,y, smallest;
  printf("Enter the 1st value: ");
  scanf("%d",&x);
  printf("%d\n",x); //to make sure it shows up on the serial monitor.
  printf("Enter the 2nd value: ");
  scanf("%d",&y);
  printf("%d\n",y); //to make sure it shows up on the serial monitor.
  
  smallest = get_smallest(x,y);
