What is "call by reference" when passing arguments to a function?

• Passing a copy of the argument.

• Passing the address of the argument

• Passing a reference to the argument

• Passing a default value

Which of the following best describes a recursive function?

• A function that calls itself to solve a problem.

• A function that only takes one argument.

• A function that doesn't return any value.

• A function that can't be called from other functions.

In C, which keyword is used to explicitly return a value from a function?

• exit

• break

• return

• continue

What is the role of the return statement in a function?

• To specify the data types of the arguments

• To declare the function's prototype

• To terminate the program

• To return a value from the function

In C, what is the purpose of the "void" keyword in a function prototype?

• It indicates the function has no arguments.

• It indicate the function has no return value.

• It denotes a recursive function.

• It defines a function without a specific return type.

What is the purpose of a function prototype in C?

• To define the function

• To declare the function's return type and parameters

• To specify the function's implementation

• To document the function's behaviour

Which part of a function definition specifies the data type of the value the function returns?

• Function name

• Function prototype

• Return type

• Arguments

What is a function call?

• A function declaration

• A function definition

• A function invocation

• A function prototype

Which of the following is an example of a function call in C?

• int main() { return 0; }

• int add(int a, int b) { return a + b; }

• add(3, 5);

• int sum = add(3, 5);

. In "call by value," the function receives:

• A reference to the original variable

• A copy of the original variable's value

• The address of the original variable

• The original variable itself
