What is a function declaration in C?

• A function declaration in C does not require parameters

• A function declaration in C specifies only the function name

• A function declaration in C defines a global variable

• A function declaration in C specifies the return type of the function, its name, and the parameters it receives.

What is the syntax to define a function in C?

• return_type function_name { function_body }

• return_type function_name(parameters) function_body

• return_type function_name(parameters) { function_body }

• return_type function_name(parameters) { }

Why is the use of function prototypes important in C?

• To improve the readability of the source code.

• To allow the compiler to verify the consistency between the function declaration and its implementation.

• To reduce the amount of memory used by the program.

• To increase the speed of program execution.

What are the parameters of a function in C?

• The parameters of a function in C are variables used to pass values to the function when called.

• The parameters of a function in C are constants that cannot be modified

• The parameters of a function in C are only used to return values from the function

• The parameters of a function in C are declared at the end of the function

What is the return type of a function in C?

• The return type is specified with the keyword 'return' followed by the corresponding data type.

• The return type is specified with the keyword 'output' followed by the corresponding data type.

• The return type is specified with the keyword 'result' followed by the corresponding data type.

• The return type is specified with the keyword 'type' followed by the corresponding data type.

What is the difference between a function declaration and a function definition in C?

• What is the difference between a function declaration and a function definition in C?

• A function declaration provides information about the name and parameters of the function, while a function definition includes the body of the function with the actual instructions.

• A function definition provides information about the name and parameters of the function.

• A function declaration and a function definition are the same in C.

What happens if a function prototype is not provided in C?

• What happens if a function prototype is not provided in C?

• The compiler will assume the function returns an integer and takes an undefined number of arguments.

• The function will return a boolean value by default

• The function will execute smoothly

What is the correct way to pass arguments to a function in C?

• The arguments are passed to a function in C using double quotes

• The arguments are passed to a function in C separated by white spaces

• The arguments are passed to a function in C within brackets

• The arguments are passed to a function in C separated by commas inside the function call parentheses.

Can a function in C return multiple values?

• Depends on the compiler

• No

• Yes, always

• Only in old versions of C

What happens if the return type specified in the function declaration does not match the actual return type in the function definition in C?

• It will result in a compilation error.

• It will result in a runtime error.

• It will automatically convert the return type.

• It will print a warning message.
