Snippet to determine the defined sizes of C data types on any machine

// Determine ranges of short,int,long (unsigned/signed) and char by implementation

#include <stdio.h>
#include <limits.h> // Defines size constants for integral typs
#include <float.h> // Defines floating-point-arithmetic related parameters

void main()
{
    printf("The range of %d bit char values: %d to %d", CHAR_BIT, CHAR_MIN, CHAR_MAX); // These are #defines in the header
    printf("\nThe range of signed char values: %d to %d", SCHAR_MIN, SCHAR_MAX);
