In your programming journey, there will come a time when you’ll want to start working with real-world data. This kind of data is typically stored in files on disk. Since reading from files involves interacting with your operating system, it amounts to a rather complex task. In this article, we’ll look at C++ streams, file handling, and three different methods for reading data from a file into a C++ program.
If you come from a high-level programming language like Python, reading a file into a program seems like a simple enough task. You open the file, read its contents and close it. Working with a file might take up one or two lines of your code. In C++, the workflow of reading a file is a bit more complex — there is the added step of reading to or from a stream object. To understand how our C++ programs interact with files, let us now take a look at the concept of streams in C++.
CSS Tabs provide helpful navigation of websites. If you have multiple web pages on your site and you want to make sure the viewers to your site are able to easily navigate to your other pages, then this is for you.
CSS Tabs use both HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets). As you know from previous tutorials, HTML is the foundational code used to structure a web page and its content, while CSS is used to enhance your web page with creative design aspects.
In this tutorial, I will take you through a lesson on creating different types of tabs in HTML, and I will also assist you in adding some creative design elements. All you need to start with is a simple code editor such as Notepad ++, which is free.
Welcome to the HTML hub! This guide will provide you with an exhaustive list of everything that you need to know about HTML— one of the most vital programming languages for creating and designing web pages today.
You’ll find everything from HTML basics, to creative more advanced HTML techniques in this guide. This is a living document so please come back and visit us as we continue to add more published content.
Most coding revolves around inputting data into something like an integrated development environment (IDE) to create a program that accomplishes a task. However, you’ll likely need that program to output data at some point. In this guide, we’ll look at how to print text in C++, covering ways to print a string and best format them.
What Is a String?
A C++ string is a variable that stores a sequence of characters, usually representing a word or phrase. We can call upon this variable later for use in our program by using the string command. If we’re looking to output a string, we can type the string we want to print directly into our program without first storing it as a variable. Here is an example:
Think of your favorite sports team. All of its players are unique and we can order them by their jersey numbers. We can refer to the players directly by name or by their number.
A similar concept exists in programming: We can organize a set number of unique values based on a predetermined order. In C++, this type of data structure is called a set.
In this article, we’ll explore what C++ sets are and how to use them, before presenting scenarios in which we would and would not use sets.
What Is a Set in C++?
A set is a data structure that stores unique elements of the same type in a sorted order. Each value is a key, which means that we access each value using the value itself. With arrays, on the other hand, we access each value by its position in the container (the index). Accordingly, each value in a set must be unique.
Learning a new skill can be a great experience but it takes time and you have to stick with it.. Every now and then it is a great idea to sit back and have a bit of fun with the material. In this article, you will do just that with some fun CSS code examples.
Topics like how to make text bold or size an image have merits in design. As do many of the other topics covered in the Udacity CSS Content Hub. However, this post will deal with simple bits of fun you can have when learning to use HTML and CSS.
With no goal in mind other than having a good time, get ready for some interesting CSS code examples to play around with.
