Taille en mémoire des types élémentaires

#include <stdio.h>
main() {
printf("Size in bytes:\n");
printf("\t char: %d\n", sizeof (char));
printf("\t short: %d\n", sizeof (short));
printf("\t int: %d\n", sizeof (int));
printf("\t long: %d\n", sizeof (long));
printf("\t long long: %d\n", sizeof (long long));
printf("\t float: %d\n", sizeof (float));
printf("\t double: %d\n", sizeof (double));
printf("\t long double: %d\n", sizeof (long double));
printf("\t void *: %d\n", sizeof (void *));
}

$ gcc -o sizeof sizeof.c
$ ./sizeof
Size in bytes:
	        char: 1
	       short: 2
	         int: 4
	        long: 4
	   long long: 8
	       float: 4
	      double: 8
	 long double: 12
	      void *: 4
