What is flag in c language?

Answer 1

In C Programming, a flag is a variable used to indicate a specific condition or state within a program. It is typically a boolean variable (often an int or bool) that can be set to true (1) or false (0) to control the flow of execution, such as in loops or conditional statements. Flags are commonly used for error checking, status reporting, or to signal when certain events have occurred. By using flags, programmers can manage complex logic more efficiently.
