Which of the following is used to store the return address of function calls?

Explanation: The computer points to the return address of the subroutine. Explanation: The registers store the return address of the routine and the computer points to it.

What is the best way to store the return address of the subroutine?

Because the last subroutine called is the first to be returned (last in first out). Therefore, the stack data structure is the most efficient way to store the return addresses of subroutines.

How many return statements can a Mcq function have?

The body of a function should only have one return statement.

What is the most suitable data structure for storing return addresses in the case of nested subroutines?


Which representation is more efficient?

Which representation is more efficient for performing arithmetic operations on numbers? Explanation: The two's complement form is more suitable for performing arithmetic operations, since the sign of the number does not need to be taken into account.

When a subroutine is called, the return address is stored in the ?

On older machines such as the DEC PDP-8 and the CDC-3300 and CDC-6000 series, the return address of a subroutine call was stored in the first word of the subroutine and the first executable statement of the subroutine was in the second. word

The CALL Instruction in the 8086 Microprocessor The address of the next instruction that exists in the calling program (after the program's CALL instruction) is stored on the stack. The instruction queue is emptied to accommodate the procedure instructions.

What is subroutine call and return?

CALL and RETURN Statements The CALL statement interrupts the flow of a program by passing control to an internal or external subroutine. An external subroutine is another program. The RETURN statement returns control from a subroutine to the calling program and optionally returns a value.

How is the stack used for calling and returning subroutines?

Stack: Calling a Subroutine Often, a subroutine needs to be passed information to perform its task. The return operation will pop the stack call address and, if necessary, PUSH a return value onto the stack. Control now returns to the statement at the calling address.

How does the stack look in function calls?

When a function call is made, the function's arguments are pushed onto the stack. These arguments are further referenced with the base pointer. When the function returns to the caller, the arguments of the returning function are popped from the stack using the LIFO method.

What is the purpose of the call stack?

The purpose of the call stack is to let you see exactly which call caused a problem. When you look at the stack trace on an exception, you can see the original call that caused the error.

When a function is called a stack is it used to store?

When a function is called, local variables are stored on a stack and automatically destroyed upon return. A stack is used when a variable is not used outside of this function. It allows you to control how memory is allocated and deallocated.

Does Python have a call stack?

The Python interpreter uses a call stack to run a Python program. When a function is called in Python, a new frame is sent to the call stack for local execution, and every time a function call returns, its frame is popped off the call stack.

What is a call stack in Python?

The call stack is what a program uses to keep track of method calls. The call stack is made up of stack frames, one for each method call. For example, suppose we called a method that rolled two dice and printed the sum. def roll_die(): return random.

What is the method call stack?

The method call stack (sometimes called the program execution stack) is a data structure that works behind the scenes to support the method call/return mechanism. It also supports the creation, maintenance and destruction of the local variables of each called method.

A stack frame represents a single function call. You can view functions that call each other as virtual frames stacked on top of each other. The stack data structure is actually used for this! When a function call returns its data to the caller, then its stack frame is removed from the stack.

How is the stack used in recursion?

Thus, in recursion, the last function called must be completed first. Now Stack is a LIFO data structure i.e. ( Last In First Out) and hence it is used to implement recursion. High-level programming languages such as Pascal, C, etc. that provide support for recursion use the stack for accounting.

What is tail recursion in Python?

python programming. Some programming languages are queue recursive, basically this means that they are able to optimize functions that return the result of calling themselves. That is, the function only returns a call to itself.

What is Python framework?

The Python Tkinter Frame widget is used to organize the widget group. It acts as a container that can be used to contain other widgets. Rectangular areas of the screen are used to arrange widgets in the Python application. The syntax for using the Frame widget is shown below.

Can web applications be built with Python?

Python can be used to create server-side web applications. However, most Python developers write their web applications using a combination of Python and JavaScript. Python runs on the server side while JavaScript is downloaded to the client and executed by the web browser.

Is PyCharm a framework?

Web Frameworks PyCharm makes it easy to develop web applications by inheriting all the web-related functionality of IntelliJ IDEA, including support for the following technologies: JavaScript. Node. RESTful web services.

Is Python a framework?

Python is an interpreted, dynamically typed, high-level language. It also implements the basic concepts of an object-oriented programming language (OOP). Python provides support for a wide range of frameworks. Generally, two types of Python framework are used during application development.

Is PyCharm compatible with Django?

Do I need to install Python before PyCharm?

To start developing in Python with PyCharm, you need to download and install Python from python.org depending on your platform. PyCharm supports the following Python versions: Python 2: version 2.7..

The PyCharm IDE is one of the most popular editors used by professional Python developers and programmers. PyCharm's large number of features does not make this IDE difficult to use, quite the opposite. Many of the features help make Pycharm a great Python IDE for beginners.

Which IDE is best for Python beginners?

Python IDEs and code editors

What is VENV in PyCharm?

A Python virtual environment (venv) allows libraries to be installed for a single project, rather than shared among all users of the computer. PyCharm will automatically ask you if you want to install these packages as soon as you enter them…
