C-format is a type of data format used primarily in programming and computer science. It is often associated with the C programming language, which utilizes this format for input and output operations. C-format allows developers to specify how data should be formatted when displayed or read, using placeholders for variables. In C-format, specific characters, such as %d for integers or %f for floating-point numbers, are used to indicate the type of data being processed. This makes it easier to manage and display information in a structured way, ensuring that data is presented clearly and accurately in applications and software development.
