Questions and Answers

What does a function prototype declare in C programming?

  • The signature of a function (correct)
  • The input for a function
  • The implementation of a function
  • The memory allocation for a function
  • Why are function prototypes important in C programming?

  • They optimize the runtime performance of the program
  • They handle user input validation
  • They allow the compiler to check for errors before program execution (correct)
  • They control the flow of a program
  • What happens if a function is called with the wrong number or type of arguments in C programming?

  • The compiler will generate an error message (correct)
  • The program will ignore the function call
  • The function will automatically correct the arguments
  • The program will crash at runtime
  • What is one of the reasons to use function prototypes in C programming?

    1. What is the purpose of a function prototype in C programming?

    <p>A function prototype in C programming is used to declare the signature of a function, including its name, return type, and parameters, allowing the compiler to check for errors before the program is executed.</p> Signup and view all the answers

    1. Why are function prototypes important in C programming?

    <p>Function prototypes are important in C programming because they enable proper type checking, error handling, and modular programming by informing the compiler of the function's interface before it is called.</p> Signup and view all the answers

    1. How do function prototypes help prevent program errors in C programming?

    <p>Function prototypes help prevent program errors in C programming by allowing the compiler to generate an error message if a function is called with the wrong number or type of arguments, preventing crashes or unexpected behavior at runtime.</p> Signup and view all the answers

    1. What is the significance of using function prototypes for modular programming in C?

    <p>Using function prototypes in C enables modular programming by providing a way to declare the interface of a function before it is defined, allowing for better organization and reusability of code.</p> Signup and view all the answers

    1. In C programming, what information is included in a function prototype?

    <p>In C programming, a function prototype includes the function's name, return type, and parameters, allowing the compiler to understand the function's interface and perform proper type checking.</p> Signup and view all the answers
