printf
The `printf` function is a standard output function in the C programming language, used to display formatted text on the screen. It allows programmers to print variables, strings, and other data types in a controlled format, making it easier to read and understand the output. The function takes a format string, which specifies how to format the output, followed by a list of variables to be printed.
In addition to C, `printf` is also available in other programming languages, such as C++ and Java, often with similar syntax. The format specifiers, like `%d` for integers and `%s` for strings, help define how each variable should be displayed. This versatility makes `printf` a fundamental tool for debugging and presenting information in programming.
