setInterval(). Each function defines specific times that dynamic events should happen; they work differently and are best used in different contexts..
The value of color is immeasurable for a designer of any aptitude. In the world of website design, it can be an important selling point for both the designer and end-user alike. Any range from vibrant reds and yellows to shallow grays can make an impact on the overall experience provided by the content. Color is the proverbial hammer that can hit the design nail on the head.
Using CSS, a designer can take generally bland HTML code and transform it into something that really makes the code pop on the page. Using simple color definitions such as “red,” “blue,” or “orange” can definitely do the trick.
However, there is a massive world of color out there — with just the perfect shade you need. In this easy-to-follow guide, you will learn how to unlock those color options using the power of CSS Hex Codes.
So you’ve decided to start C++? That’s great!
You’ve taken the huge first step, but where do you go next? Writing code in C++ looks as hard as picking up Japanese. You could always self-study, but getting qualified instruction will speed up your learning process. Read on for our tips on starting your C++ journey.
Relational databases store information in tables — with columns that are analogous to elements in a data structure and rows that are one instance of that data structure. In SQL, a table cell without a value contains a special marker, NULL, which is not the same as zero, an empty string, or any other kind of value that works with equality tests; i.e.
NULL != 0,
NULL != "“, etc. The SQL Coalesce statement is one way of processing these NULL values for common uses like text processing.
We find ourselves adding, subtracting, and comparing things on a regular basis. These simple (or complex) operations are just as important in code. In C++, operators perform calculations and compute results. We rely on operators for tasks such as calculating areas and volumes of shapes, comparing values in an if/else statement and checking if a statement is true or false.
C++ likely would not exist without classes. As the original C programming language grew more decipherable, C++ was born. Because C++ was built entirely with objects in mind, C++ uses classes to make it easy to work with objects. Classes and objects became the building blocks C++ uses for creating streamlined and easy-to-read code.
What exactly is a C++ class, and how does it tie into making it easy to use, follow and compile code? We’re glad you asked.
