And also C based on the same idea as my Python (but this has to ? for 0s):

    int i;
    char* a[] = { 0, "Buzz", "Fizz", "FizzBuzz" };
    char* f[] = { "%s\n", "%d\n" };
    for ( i = 1; i < 101; i++ ) {
        char* s = a[ (i%3==0)*2 + (i%5==0) ];
        printf( f[!s], s ? s : i );
    }

Don't ruin that version with an if statement.

Use this and avoid it( and the second array as well ):

  char * a[] = { "%d\n" , "Fizz\n" , "Buzz\n" , "FizzBuzz\n" } ;

Brilliant, thanks! The C version is now:

    int i; char* a[] = { "%d\n", "Fizz\n", "Buzz\n", "FizzBuzz\n" };
    for ( i = 1; i < 101; i++ )
        printf( a[ (i%5==0)*2 + (i%3==0) ], i );
