Work With Text Files in C++: A Guide in Programming

In this guide, we will learn the features of text files and learn how to use them in C++ programming.

Opening and closing text files

A text file is a collection of strings with the character of a changeable length. Each line ends with the end marker of the string – a special pair of control characters, the codes of which are: 13 (carriage return) and 10 (newline). At the end of the file, there is always an end of file marker – a control character with code 26. Continue reading

Python Email Example – An Easy Instruction

In our Python email example, we write about creating email using Python. In the modern world people get a lot of letters, and some even have several mailboxes. All this complicates the process of administration, which forces us to seek solutions to the problem. Motherboard editor Michael Byrne wrote a story on how to send emails to different mailboxes using Python. Even if you do not want to create a letter sorting program, managing emails as a set of data is quite interesting. Byrne decided to use Python to solve the problem, since this language is good for easy and intuitive creation of such things, and is suitable even for non-programmers. Continue reading

Spectral Graph Theory Sample

The spectral graph theory studies the properties of graphs by means of an analysis of eigenvalues / eigenvectors / of characteristic polynomials of matrices that are connected with graphs (conjugacy matrix, Laplace matrix, unsigned Laplace matrix, etc.). The theory was actively developed in the 1970s, but now finds application in the analysis of graphs of social networks. The theory is related to the detection of communities and the partitioning of graphs. The sample that you will find below will be devoted to theoretical aspects (even proofs), and will be useful for applicants to understand why certain methods of generating features (based on spectra) are working.

Histogram Example for Math Students

The histogram example is used to display the interval series. In order to construct a histogram from the data of the variational series at equal intervals, as for the construction of the polygon, the values of the argument are plotted on the abscissa axis and the frequencies or relative frequencies are plotted on the ordinate. Next, rectangles are constructed whose bases are segments of the abscissa, whose lengths are equal to the lengths of the intervals, and the heights are segments whose lengths are proportional to the frequencies or relative frequencies of the corresponding intervals.

While Loop MATLAB Example Completed by an Expert

Repetition is an algorithmic design that represents a sequence of actions that are performed repeatedly. Algorithms containing a repetition construct are called cyclic, or cycles. The sequence of actions that repeats during the execution of a cycle is called the body of a cycle (or loop). A loop with a given continuation condition is programmed in Pascal using the “while” operator. Sometimes when solving problems, it becomes necessary to perform the body of the loop at least once, and then to investigate the condition to repeat it again. You can go deeper in this question if you check out the following while loop matlab sample.

The while loop example presented here can help you with your own assignment. This sample cannot be presented by you as your own work (unless you will order MATLAB assignment help from us). You can structure your assignment the same as our example. You can also find other samples in our blog that will help you with your tasks. Determine whether you need the following or any other sample, and feel free to use them for your purposes. Continue reading

A Unified Modeling Language Example to Help You Out

Unified Modeling Language (UML) is the standard tool for creating “blueprints” of software. Using UML, you can visualize, specify, design, and document artifacts of software systems. UML examples are suitable for modeling any system: from enterprise-wide information systems to distributed web applications and even embedded real-time systems. This is a very expressive language, allowing you to view the system from all points of view, relevant to its development and subsequent deployment. UML is a language for visualizing, specifying, constructing, and documenting artifacts of software systems. The language consists of a dictionary and rules that allow you to combine the words included in it and get meaningful constructions.

In the Unified Modeling Language example that we present, you can find ideas on how to deal with your own assignment. If you need to complete a task on a similar topic, the sample will greatly help you. Reading through the example is necessary to understand the issue. In any case, the following sample will be helpful. Continue reading

Python – Working With Files

In this example of Python working with files, we’ll look at the built-in Python tools for working with files: opening / closing, reading, and writing. Until now, we only worked with objects stored in the computer’s RAM. That is, after the completion of the program, all our actions were deleted. Using our sample, you will learn how to work with files in Python, that is, to save the state of the program in a file on the hard disk.

Before you start working on your assignment, you should read through our sample. You can use our sample on Python write to file, as well as for doing any other tasks easily. If you don’t know how to complete your assignment, visit our blog to find the sample that you need. We have examples for tasks of different disciplines. Once you read, for example, the following sample, you will have a clearer understanding on how to do your own task in Python. Continue reading

Sample of a Python User Defined Function

In the following sample, we are going to talk about Python user defined function. A function in Python is an object that takes arguments and returns a value. A function is a block of organized, reusable code that is used to perform a specific task. Functions provide better modularity of the application and significantly increase the level of code reuse. There are some rules for creating functions in Python. You will learn about these rules if you read through the following sample.

We advise all students who are starting to study programming to read it through. Also, you can find examples of completed assignments in other disciplines. After you read our sample, you will be able to work with user defined functions in Python. You will see that such functions can be easily created by you. So, don’t wait anymore and read the following example – it will surely be helpful for you.

Detailed Python String Format Example

Sometimes (more precisely, quite often), there are situations where you need to make a string, substituting in it some data obtained during the execution of the program (user input, data from files, etc.). Data substitution can be done by formatting strings. Formatting can be done using the % operator, and the format method. The format method is the most correct, but you can often come across a program code with string formatting in the form of the operator %. If you read through the following Python string format example, you will easily complete your own assignment.

The Python string functions example that you can find below was completed by an expert in programming. Why do you need this sample? Such tasks are often assigned to students – that’s why we have decided to help you with this problem. If you need help with other types of assignments, you can check out our blog to find more samples. Continue reading

Look at This Python GUI Example

One attractive feature of Python is the simplicity, speed, and flexibility in creating applications with a graphical user interface (GUI). This advantage is associated not only with a large number of supported graphic libraries: Tkinter, PyQt, PyGTK, wxPython, Pygames, etc. The main reason is the interpretive nature of the Python platform; because of the availability of Python code, the appearance of the graphical application can always be changed or supplemented. And the entire interface from the Python code to the actual implementation of the GUI is hidden inside the Python library modules. Check out our Python GUI example to know about more advantages of developing GUI applications in Python.

The Python GUI sample presented below was developed by an expert in programming. You will complete your own task much faster if you read through our example and get some ideas from it. Because of the ease of demonstrating the problem and its solution, any student can understand the example. The sample is available for you now, so enjoy reading! Continue reading
