In the previous topic, we have discussed data types in C++ in detail. Today we will discuss variables and constants in C++.
A named memory location or memory cell is called a variable. The program's input data and its results are stored in variables during execution. During the execution of the program, the value of a variable can be changed but its name can not be changed.
Variables are created in random access memory. As we know that RAM is a temporary memory so data stored in it is also temporary. It can only be used during execution. When the program ends, the data stored in the variable is automatically removed.
In C++, all the variables are declared first:
Name of variable: an identifier that represents a memory location.
Address of v ...
In the previous section, we have had an overview of a detailed Introduction to C++. Today, we will have a look at the data types in C++. It's our 2nd tutorial in the C++ programming language series.
In the previous tutorial, we have seen the basics of C++ and have also discussed a small code. We have discussed various programming terms in the previous tutorial and from now on, we are going to discuss those terms in detail. So, today's lecture is on Data Types in C++, let's get started:
C++ Data Types
A data type defines the type and the set of operations that can be performed on the data. Various types of data are manipulated by the computer. The data is given as an input to the program. According to the program's set of instructions, data is pr ...
Hello friends, I hope you all are doing great. Today, we will create a wifi temperature monitoring system. For reading, we will use the DS18B20 sensor. For data processing and webpage creation, we will use our already known ESP8266.
The project will be built as follows:
Circuit assembly
Code for reading the DS18B20 sensor (we will use Serial for tests).
Creation of the webpage (we will use SPIFFS to store in FLASH).
But first, let's know a little about the sensor and the communication model it uses.
Materials
For this project, we will need the following items: For this project, we will need the following items:
1 x ESP8266
1x DS18B20 Sensor
1x Breadboard
1x 4k7 Ohms resistor
DS18B20
DS18B20 is a digital temperature sensor with good precision, good customization, pr ...

3D modeling has been evolving since the day it came into the limelight. Within years of efforts, the technology has changed tremendously, offering better prospects and possibilities to the users. And, the development within the 3D modeling niche does not seem to cease. There are many interesting upgrades already underway and many to come in the years to follow.
Undoubtedly, the future of technology looks much brighter, with virtual reality and 3D printing furthering the application of 3D design and inventive engineering at a higher pace. It won’t be an exaggeration to deem that the increased accessibility of 3D printing did have a great impact on 3D design. In addition to shortening the time needed to create prototypes, additive manufacturing enab ...
The ongoing developments of technology have changed multiple industries, and possibly none more so than manufacturing. Over the years, each new machine and AI discovery has been implemented into factories all around the globe, allowing processes to move faster, more efficiently, and at a lower cost. Want to learn more? Here is how technology has changed the manufacturing industry.
A Faster Service
With technology constantly improving machines, the amount of time the manufacturing processes take has greatly lowered. There are plenty of brilliant machines designed for increased productivity on the market, including ones like a speedy engraving machine, which ensures both quality and efficiency.
Automation is another way technology has contributed t ...
The Internet of Things (IoT) philosophy may be viewed as a highly dynamic and radically dispersed networked system comprised of a huge number of identifiable smart devices. These objects may communicate and interact with one another, as well as with end-users and other network entities. As the Internet of Things era begins, the usage of small, inexpensive, and flexible computer hardware that allows end-user programming becomes more prevalent. The Raspberry Pi, a fully configurable and programmable tiny computer board, is one of them discussed in this article. Although there are certain limitations, the Raspberry Pi remains a low-cost computer that has been used effectively in a wide range of IoT vision research applications despite its few shortcomings.

Hello friends, I hope you all are doing great. In today's tutorial, I am going to give you a detailed introduction to the C++ Programming language. In cross-platform programming languages, C++ is the most popular that can be used to work on low and high-level applications. Bjarne Stroustrup was the founder of C++. He modified C language to develop C++ language. Control over system resources and memory can be attained by using C++. In 2011, 2014, and 2017 it was modified to C++11, C++14, and C++17. C++ is a middle-level language. It is advantageous to both programming languages low-level (drivers, kernels) and higher-level applications (games, GUI, desktop apps etc.).
Uses of C++
C++ is one of the world's most famous programming languages. It is u ...
For the legions of YouTube content creators all competing for attention, the art of attracting more subscribers often feels complicated and mysterious. Successful accounts usually make great videos, but quality alone is rarely enough to reach influencer status.
In this article, we take a look at ten proven and practical ways to get more subscribers on YouTube. Want to buy cheap subscribers and become famous? Read on to find out how to make it happen.
Ask & Receive
One thing that most successful videos do? They ask their viewers to subscribe. You may notice that a lot of your content receives more likes, comments, and views than it does new subscribers. Mysterious? Not necessarily.
Keep in mind that about 5 billion YouTube views take place eve ...
