printf unsigned int code example

Example 1: c printf

/* printf example */
#include <stdio.h>

int main()
{
   printf ("Characters: %c %c \n", 'a', 65);
   printf ("Decimals: %d %ld\n", 1977, 650000L);
   printf ("Preceding with blanks: %10d \n", 1977);
   printf ("Preceding with zeros: %010d \n", 1977);
   printf ("Some different radices: %d %x %o %#x %#o \n", 100, 100, 100, 100, 100);
   printf ("floats: %4.2f %+.0e %E \n", 3.1416, 3.1416, 3.1416);
   printf ("Width trick: %*d \n", 5, 10);
   printf ("%s \n", "A string");
   return 0;
}

Example 2: printf signed char

%c   --- char
%hh  --- signed char (synomous with char)
%hhu --- unsigned char
%h   --- short
%hu  --- unsigned short
%d   --- int
%u   --- unsigned int
%lu  --- unsigned long (including size_t, which is returned by sizeof())
