What is a function return type? The data type of the value a function returns The name of the function The input parameters of a function The function's execution time

The data type of the value a function returns

What is typically the purpose of a function's return value? To execute a loop To provide output for further processing To read user input To define variables

To provide output for further processing

In Python, what does the 'return' statement do? It stops the function execution and outputs a result It prints a message to the console It creates a new variable It loops through a list

It stops the function execution and outputs a result

What is a common misconception about function return types? Functions can only return integers Functions can return various data types Functions cannot return complex structures Return types must match function parameters

Functions can only return integers

What is the primary purpose of a return type in a function? To specify the type of value the function will return To define the number of arguments the function accepts To indicate the function's execution speed To determine the operating system compatibility

To specify the type of value the function will return

How can a function return multiple values using a complex data structure? By returning a dictionary or map By returning a boolean value By returning a single integer By returning a null value

By returning a dictionary or map

When a function returns a pointer, what must be ensured to avoid undefined behavior? The pointer is initialized The pointer points to valid memory The pointer is a constant The pointer is null

The pointer points to valid memory

How does a function in Python differ in return type compared to a statically typed language like C? Python functions always return a list Python functions return a fixed type Python functions can return any data type Python functions do not require a return statement

Python functions can return any data type

Which of the following statements is true about the return type of a recursive function? It must return an integer It can be void It should match the return type of its recursive calls It cannot return a data structure

It should match the return type of its recursive calls

In functional programming, what is the significance of a function returning another function? It allows for memory management It enables higher-order functions It restricts the use of variables It prevents errors

It enables higher-order functions

What is the main characteristic of pass-by-value in parameter passing? A copy of the argument's value is passed. A reference to the actual argument is passed. No data is passed to the function. The function can modify the original data.

A copy of the argument's value is passed.

What is a potential drawback of pass-by-reference? It uses more memory. It can lead to unintentional data modification. It is slower than pass-by-value. It does not support complex data types.

It can lead to unintentional data modification.

Which of the following is an advantage of pass-by-value? Ensures the original data remains unchanged Allows direct modification of the original data Uses less memory overall Increases function execution speed

Ensures the original data remains unchanged

What is the main advantage of using pass-by-reference? Less memory usage Faster execution time Ability to modify the original data Improved data security

Ability to modify the original data

What is pass-by-value in parameter passing? A copy of the actual parameter's value is passed. A reference to the actual parameter is passed. Parameters are passed using pointers. Parameters are passed using address space.

A copy of the actual parameter's value is passed.
