16.2.7 Table of Output Conversions
Here is a table summarizing what all the different conversions do:
- `%d', `%i'
- Print an integer as a signed decimal number. Patrz Integer Conversions, for details. `%d' and `%i' are synonymous for
output, but are different when used with
scanf
for input
(see Table of Input Conversions).
- `%o'
- Print an integer as an unsigned octal number. Patrz Integer Conversions, for details.
- `%u'
- Print an integer as an unsigned decimal number. Patrz Integer Conversions, for details.
- `%x', `%X'
- Print an integer as an unsigned hexadecimal number. `%x' uses
lower-case letters and `%X' uses upper-case. Patrz Integer Conversions, for details.
- `%f'
- Print a floating-point number in normal (fixed-point) notation.
Patrz Floating-Point Conversions, for details.
- `%e', `%E'
- Print a floating-point number in exponential notation. `%e' uses
lower-case letters and `%E' uses upper-case. Patrz Floating-Point Conversions, for details.
- `%g', `%G'
- Print a floating-point number in either normal (fixed-point) or
exponential notation, whichever is more appropriate for its magnitude.
`%g' uses lower-case letters and `%G' uses upper-case.
Patrz Floating-Point Conversions, for details.
- `%c'
- Print a single character. Patrz Other Output Conversions.
- `%s'
- Print a string. Patrz Other Output Conversions.
- `%%'
- Print a literal `%' character. Patrz Other Output Conversions.
If the syntax of a conversion specification is invalid, unpredictable
things will happen, so don't do this. If there aren't enough function
arguments provided to supply values for all the conversion
specifications in the template string, or if the arguments are not of
the correct types, the results are unpredictable. If you supply more
arguments than conversion specifications, the extra argument values are
simply ignored; this is sometimes useful.
