This section describes miscellaneous conversions for printf
.
The %c
conversion prints a single character. The -
flag can be used to specify left-justification in the field, but no
other flags are defined, and no precision or type modifier can be given.
For example:
printf ("%c%c%c%c%c", "h", "e", "l", "l", "o");
prints hello
.
The %s
conversion prints a string. The corresponding argument
must be a string. A precision can be specified to indicate the maximum
number of characters to write; otherwise characters in the string up to
but not including the terminating null character are written to the
output stream. The -
flag can be used to specify
left-justification in the field, but no other flags or type modifiers
are defined for this conversion. For example:
printf ("%3s%-6s", "no", "where");
prints nowhere
(note the leading and trailing spaces).
