h> header file. Note: More accurately, it writes to the location specified by stdout which is usually the console but it may be configured to point to a file or other location. Code such as printf (foo); often indicates a bug, since foo may contain a % character. Writes the C string pointed by format to the standard output (stdout). It allows for versatile printing of variables, strings, and other data types. Oct 3, 2025 · Describes the format specifier syntax for the Microsoft C runtime `printf` and `wprintf` functions Oct 18, 2025 · In C language, printf () function is used to print formatted output to the standard output stdout (which is generally the console screen). The C library printf () function is a fundamental tool for outputting formatted text to the standard output stream. It can optionally contain embedded format printf is a C standard library function and is also a Linux terminal (shell) command that formats text and writes it to standard output. Jul 28, 2024 · Summary: This page is a printf formatting cheat sheet or reference page. h>. Apr 6, 2025 · This tutorial has explored the versatile printf function in C. . The function accepts a format C-string argument and a variable number of value arguments that the function serializes per the format string. May 23, 2024 · As with all bounds-checked functions, printf_s, fprintf_s, sprintf_s, and snprintf_s are only guaranteed to be available if __STDC_LIB_EXT1__ is defined by the implementation and if the user defines __STDC_WANT_LIB_EXT1__ to the integer constant 1 before including <stdio. If format includes format specifiers (subsequences beginning with %), the additional arguments following format are formatted and inserted in the resulting string replacing their respective specifiers. If foo comes from untrusted user input, it may contain %n, causing the printf () call to write to memory and creating a security hole. May 23, 2024 · As with all bounds-checked functions, printf_s, fprintf_s, sprintf_s, and snprintf_s are only guaranteed to be available if __STDC_LIB_EXT1__ is defined by the implementation and if the user defines __STDC_WANT_LIB_EXT1__ to the integer constant 1 before including <stdio. The printf() function is defined in the <stdio. From basic text output to advanced formatting, printf is essential for clear program communication. I originally created this printf cheat sheet for my own programming purposes, and then thought it might be helpful to share it here. Parameters format C string that contains the text to be written to stdout.
