Article Summary
`printf` in C is a standard library function that outputs formatted text to the console. This article covers syntax, format specifiers, escape sequences, field width, and common pitfalls. You'll gain the practical knowledge to use `printf` in C confidently from day one.
Two of the first functions a C programmer will learn are “printf()” and “fprintf().” The printf() function governs output to the user’s monitor, while fprintf() governs output to a file instead. Both printf() and fprintf() operate similarly (and their arguments may be interchangeable), but most C programmers will find themselves using printf() most frequently.
In this article, we’ll discuss when you would use the printf() function, how to use it, and what the most common issues encountered might be. The printf() function is easy enough for beginners in C to learn — and it’s very similar to the “print formatted” functions in many other languages.
