stdio_test.c - demonstrates use of ‘scanf’ forms

This program requires inclusion of “pic24_stdio_uart.c”.

 
#include "pic24_all.h"
#include <stdio.h>

  printf ("This tests 'scanf' stdio; all entries must be terminated by a newline\n");
  printf("Input a string (< 63 characters: ");
  scanf("%s",sz_1);          //get a string from the console
  printf("\n");
  printf("Entered: '%s' \n",sz_1);

  printf("Input an unsigned decimal number: ");
  printf("\n");
  scanf("%lu",&ui32_k);
  printf("The number is: %lu\n",ui32_k);
