Write a program to determine the ranges of char , short , int , and long variables, both signed and unsigned , by printing appropriate values from standard headers and by direct computation. Harder if you compute them: determine the ranges of the various floating-point types. 



#include <stdio.h>
#include <limits.h>

int 
main ()
{
  printf("Size of Char %d\n", CHAR_BIT);
  printf("Size of Char Max %d\n", CHAR_MAX);
  printf("Size of Char Min %d\n", CHAR_MIN);
  printf("Size of int min %d\n", INT_MIN);
  printf("Size of int max %d\n", INT_MAX);
  printf("Size of long min %ld\n", LONG_MIN);       /* RB */
  printf("Size of long max %ld\n", LONG_MAX);       /* RB */
  printf("Size of short min %d\n", SHRT_MIN);
  printf("Size of short max %d\n", SHRT_MAX);
  printf("Size of unsigned char %u\n", UCHAR_MAX);  /* SF */
  printf("Size of unsigned long %lu\n", ULONG_MAX); /* RB */
  printf("Size of unsigned int %u\n", UINT_MAX);    /* RB */
  printf("Size of unsigned short %u\n", USHRT_MAX); /* SF */

  return 0;
}
