Basic C Programming - Function parameter

What is the syntax for declaring a function in C?

• parameters function_name(return_type)

• return_type function_name(parameters)

• return_type function_name(parameters);

• function_name(parameters) return_type

How do you define a function in C?

• function_name(Parameters) { // Function body }

• Return_Type Parameters function_name { // Function body }

• function_name(Parameters) { // Function body } Return_Type

• Return_Type function_name(Parameters) { // Function body }

What is a function prototype in C?

• A function prototype in C is a declaration of a function that specifies only the function's name.

• A function prototype in C is a definition of a function that includes the function body.

• A function prototype in C is a declaration of a function that specifies the function's name and return type but not the parameters.

• A function prototype in C is a declaration of a function that specifies the function's name, return type, and parameters without providing the function body.

Explain pass by value in C with an example.

• In C, pass by value is demonstrated by passing variables to a function and modifying them inside the function. The original variables remain unchanged after the function call.

• Pass by value in C involves passing pointers to variables

• Pass by value in C allows direct modification of original variables inside a function

• Pass by value in C means passing variables to a function without modifying them

What is the purpose of the return statement in a function in C?

• To print a message on the console

• To terminate the function and return a value

• To skip the function and move to the next one

• To pause the execution of the program

How do you declare a function that takes two integer parameters in C?

• void functionName(int param1, int param2)

• int functionName(int param1, int param2)

• void functionName(int param1; int param2)

• void functionName(param1, param2)

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

• Function declaration specifies the function signature, while function definition includes the implementation.

• Function declaration includes the implementation, while function definition specifies the signature.

• Function declaration and function definition are interchangeable terms in C.

• Function declaration defines the function signature, while function definition specifies the implementation.

Can a function in C return multiple values? If yes, how?

• No

• Yes, by using function overloading

• Yes, by using global variables

• Yes, by using pointers

What happens if a function in C is called before it is declared or defined?

• The function will execute successfully

• The function will be skipped

• The function will be automatically declared

• The compiler will throw an error

Explain the concept of function overloading in C.

• Function overloading in C is achieved by defining multiple functions with the same name but different parameter lists.

• Function overloading in C is achieved by defining multiple functions with different names but the same parameter list.

• Function overloading in C is achieved by defining a single function with multiple return types.

• Function overloading in C is achieved by defining multiple functions with the same name and the same parameter list.
