The POSIX man page of printf(1) mentions -
> If the format operand contains no conversion specifications and
> argument operands are present, the results are unspecified.
In practice, this means some printf implementations throw an error
when provided with extra operands, thereby causing the test to fail
erroneously. This commit fixes that issue.
This commit also eliminates the for-loops surrounding said printf
statements in favour of the built-in functionality of printf to consume
all arguments by reusing the format operand as-often-as-necessary.
This behaviour is mentioned in the POSIX man page of printf(1) under the
section titled "EXTENDED DESCRIPTION" like so -
8. For each conversion specification that consumes an argument, the
next argument operand shall be evaluated and converted to the
appropriate type for the conversion as specified below.
9. The format operand shall be reused as often as necessary to
satisfy the argument operands. [...]
