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.h>.
Writes the C string pointed by format to the standard output (stdout). 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. Parameters format C string that contains the text to be written to stdout. It can optionally contain embedded format ...
printf is a C standard library function that formats text and writes it to standard output. The function accepts a format C-string argument and a variable number of value arguments that the function serializes per the format string.
The printf() function is defined in the <stdio.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.
The C library printf () function is a fundamental tool for outputting formatted text to the standard output stream. It allows for versatile printing of variables, strings, and other data types.
Code such as printf (foo); often indicates a bug, since foo may contain a % character. If foo comes from untrusted user input, it may contain %n, causing the printf () call to write to memory and creating a security hole.
This tutorial has explored the versatile printf function in C. From basic text output to advanced formatting, printf is essential for clear program communication.
The printf function is the main way to print out anything in C. The function signature is int printf (const char *restrict format, ...); which honestly isn't too helpful to a beginning C programmer. First of all, ignore the return value.
