These last two imply that both unsigned short int and int are at least
16 bits wide. At least, according to the standard.

 
Or, you know, just rely on the explicit definitions in stdint.h.

 
   sizeof() will give the right sizes.
 
   Simple, easy to write, 'best practice'.

#include <stdio.h>
#include <stdlib.h>


int main(void) {
    printf("sizeof(char) %ld \n", sizeof(char));
    printf("sizeof(short) %ld \n", sizeof(short));
    printf("sizeof(int) %ld \n", sizeof(int));
    printf("sizeof(long) %ld \n", sizeof(long));
    return 0;
}

$ ./sizeof
sizeof(char) 1
sizeof(short) 2
sizeof(int) 4
sizeof(long) 8
