printf is a C standard library function that formats text and writes it to standard output. The name, printf is short for print formatted where print refers to output to a printer although the functions are not limited to printer output. The standard library provides many other similar functions that form a family of printf-like functions.
They have the form \uhhhh or \Uhhhhhhhh, where h stands for a hex digit. Unlike other escape sequences, a universal character name may expand into more than one code unit. The sequence \uhhhh denotes the code point hhhh, interpreted as a hexadecimal number. The sequence \Uhhhhhhhh denotes the code point hhhhhhhh, interpreted as a hexadecimal ...
printf(string format, items-to-format) It can take one or more arguments, where the first argument is a string to be written. This string can contain special formatting codes which are replaced by items from the remainder of the arguments. For example, an integer can be printed using the "%d" formatting code, e.g.: printf("%d", 42);
In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. [32] New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for ...
For example, ADD(VALUE, 2) expands to 1 / 12 + 2. Variadic. A variadic macro (introduced with C99) accepts a varying number of arguments which is particularly useful when wrapping functions that accept a variable number of parameters, such as printf. Order of expansion. Function-like macro expansion occurs in the following stages:
C++11 is a version of a joint technical standard, ISO/IEC 14882, by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), for the C++ programming language. C++11 replaced the prior version of the C++ standard, named C++03, [1] and was later replaced by C++14.
The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3]
