For example, printf ("%3d", 12) specifies a width of 3 and outputs 12 with a space on the left to output 3 characters. The call printf ("%3d", 1234) outputs 1234 which is 4 characters long since that is the minimum width for that value even though the width specified is 3.
printf is a C function belonging to the ANSI C standard library, and included in the file stdio.h. Its purpose is to print formatted text to the standard output stream . Hence the "f" in the name stands for "formatted".
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 .
UCHAR_WIDTH, USHRT_WIDTH, UINT_WIDTH ... It defines macros for printf format string and scanf format string specifiers corresponding to the types defined in <stdint ...
The printf width specifier z is intended to format that type. sizeof cannot be used in C preprocessor expressions, such as #if, because it is an element of the programming language, not of the preprocessor syntax, which has no data types. The following example in C++ uses the operator sizeof with variadic templates.
Format is a function in Common Lisp that can produce formatted text using a format string similar to the print format string.It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance: hex, binary, octal, roman numerals, and English), apply certain format specifiers only under certain conditions, iterate over data structures ...
Arrays may have a stride larger than their elements' width in bytes in at least two cases: ... (const int * arr, int length, size_t stride) {int i; printf ...
A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.
