printk is a C function from the Linux kernel interface that prints messages to the kernel log. [1] It accepts a string parameter called the format string , which specifies a method for rendering an arbitrary number of varied data type parameter(s) into a string. [ 1 ]
In Unix and Unix-like operating systems, printf is a shell builtin (and utility program [2]) that formats and outputs text like the same-named C function. Originally named for outputting to a printer, it actually outputs to standard output. [3] The command accepts a format string, which specifies how to format values, and a list of values.
cons (e 1, l 1) = cons (e 2, l 2) if e 1 = e 2 and l 1 = l 2. Note that first (nil ()) and rest (nil ()) are not defined. These axioms are equivalent to those of the abstract stack data type. In type theory, the above definition is more simply regarded as an inductive type defined in terms of constructors: nil and cons.

The format string syntax and semantics is the same for all of the functions in the printf-like family. Mismatch between the format specifiers and count and type of values can cause a crash or vulnerability. The printf format string is complementary to the scanf format string, which provides formatted input (lexing a.k.a. parsing). Both format ...
The actual statement is in columns 7 through 72 of a line. Any non-space character in column 6 indicates that this line is a continuation of the prior line. A 'C' in column 1 indicates that this entire line is a comment. Columns 1 though 5 may contain a number which serves as a label.
There were three types of languages in the list: - printf using the same format string style (e.g. AWK) - a formatting function that had similar capabilities but a different format string style (e.g. AMPL) - a formatting function that is arguably unrelated to the spirit of printf (e.g. Python)
