What is the correct syntax to define a function in Python?

• define function_name(parameters):

• function_name(parameters) = def

• def function_name(parameters):

• function function_name(parameters)

In C, how do you declare a variable of type integer?

• int myVariable;

• var myVariable;

• integer myVariable;

• float myVariable;

What is the purpose of the 'self' keyword in Python?

• The 'self' keyword is a built-in function for string manipulation.

• The 'self' keyword is used to create static methods in a class.

• The 'self' keyword is used to refer to the instance of the class.

• The 'self' keyword is used to define a class in Python.

Explain the difference between 'malloc' and 'calloc' in C.

• 'malloc' and 'calloc' are the same function

• 'malloc' allocates memory without initialization, while 'calloc' allocates memory and initializes it to zero.

• 'malloc' allocates memory and initializes it to a random value

• 'calloc' allocates memory without any parameters

What is a pointer in C and how is it declared?

• A pointer in C is declared using the syntax 'type *pointerName;'. For example, 'int *ptr;' declares a pointer to an integer.

• A pointer in C is a variable that holds a string value.

• A pointer in C is declared using 'type pointerName;'.

• A pointer in C is declared with the syntax 'pointerName *type;'.

How do you create a list in Python?

• You create a list in Python using curly braces, e.g., my_list = {1, 2, 3}.

• You create a list in Python using parentheses, e.g., my_list = (1, 2, 3).

• You create a list in Python by using the list() function, e.g., my_list = list(1, 2, 3).

• You create a list in Python using square brackets, e.g., my_list = [1, 2, 3].

What is the output of the following Python code: print(2 ** 3)?

• 4

• 8

• 6

• 9

What is the significance of the '&' operator in C?

• The '&' operator is used to declare constants.

• The '&' operator is significant for bitwise operations and obtaining variable addresses.

• The '&' operator is only for logical operations.

• The '&' operator is used for string concatenation.

How do you access the value pointed to by a pointer in C?

• Use the address operator '&'.

• Access the value using '->'.

• Assign a value directly to the pointer.

• Use the dereference operator '*'. For example, '*ptr'.

What is the difference between a list and a tuple in Python?

• Lists are faster than tuples in all operations.

• Tuples are created using square brackets while lists use parentheses.

• The main difference is that lists are mutable and tuples are immutable.

• Lists can contain only numbers while tuples can contain any data type.
