Java

• C++ vs. Java

  C++ and Java are popular programming languages used by developers and programmers. Each of these languages has its own advantages and disadvantages but before we begin to investigate the crucial differences between the aforementioned programming languages let’s first establish our basic understanding regarding the two.

• Features of Java

  Java is a well-known high-level, server-side/backend, a class-based programming language that is easy to learn and understand. It is used in the distributed environment on the internet. The idea of java was based on creating a secure, easy-to-use, and portable programing language. This write-up will provide a detailed overview of Java features. So, let’s begin!

C++

• Std::move in C++

  To disregard or remove single or maybe more letters from the input buffer using the cin.ignore() method. Maybe we need to remove the undesirable buffer so that the next data is stored in the intended container rather than the preceding variable's cache. For instance, we must provide a character array or string after inputting the cin command. Cin.ignore() in C++ is explained with examples in this article.

• Cin.ignore() in C++

  To disregard or remove single or maybe more letters from the input buffer using the cin.ignore() method. Maybe we need to remove the undesirable buffer so that the next data is stored in the intended container rather than the preceding variable’s cache. For instance, we must provide a character array or string after inputting the cin command. As a result, we must empty the input buffer; else, the buffer of the preceding variable would be occupied. Because the cache of the preceding element lacks room to retain fresh data, hitting the “Enter” button just after the initial input ignores the container’s next input. Let’s start with the examples of the cin.ignore() function with the launch of new C++ files through the terminal shell. The file must be created through the touch instruction and the file’s name. Ubuntu’s “nano” editor has been used so far to open the file to edit.

Arduino

• What is INPUT_PULLUP in Arduino

  In Arduino, we have to define the behavior of the pins with the help of the pinMode() function that either pin should behave as an input or output. We can also define the behavior of the pin as an input_pullup, now the question that arises in mind is what this input_pullup does? The input_pullup adds built-in resistance to the electrical circuit.

  In this write-up, the utilization of the input_pullup has been explained with the help of an example.

• How to use breadboard with Arduino

  We can read the analog voltage signals from the analog I/O pins of the Arduino board and this input is converted to the digital values using the ADC. In this write-up, we have demonstrated an example of reading analog voltage input and visualized the results on a serial monitor as well as a serial plotter.

• How to read voltage in Arduino

  Read analog voltage is a technique by which we can read the analog signal of voltage from the analog I/O pins of Arduino. Analog signals are continuous signals which are varying with time like human sounds and AC(alternating current) voltage.

  In this write-up, we will discuss an example to explain how the analog voltage is read by the analogRead() function.

• Character functions in Arduino

  The character functions in Arduino programming are used to perform operation of the character data types that are used in Arduino. These functions are used to determine what type of character is used either as a number or alphabet.

• Arduino Input and Output functions

  To interface the Arduino board with different integrated chips, sensors, LEDs, and other peripherals different functions are used for the input and output. Similarly, to run the compiled code on the Arduino board these functions are also used. These input and output functions also define the inputs and outputs of the Arduino program.

• Analog Read Serial Arduino

  Sometimes we have to take input of the analog values from the sensors such as to find out the temperature of the room, the input values are in analog. These values can be read by the Arduino from its specific pins and these values can be used for further use. But before understanding the analogRead(), we have to understand what is the analog value? The analog value always varies from negative infinity to positive infinity and it is not restricted to only 0 and 1 like the digital values.

  In the above discussion, we gave an example of room temperature, the room temperature can be 35 degrees or 10 degrees. It is not restricted that the room temperature should be 0 or 1. These types of values are known as analog values. In this write-up, the analogRead() function is explained in detail with the help of which we can take analog input values in Arduino.

• Getting Started Guide of HTML – Introduction

  HTML acronym of Hypertext Markup Language is the backbone language behind each and every web page you see all over the internet to build the structure of the web pages. It is not a typical programming language rather a markup language as a set of specific instructions known as “tags” are used to construct the elements of a webpage.

• Assignment Operators in JavaScript | Explained with Examples

  Assignment operators are a crucial part of computer programming that are used to allocate the value of the left operand to the right operand or in simple words assign values to variables. Assignment operators perform logical operations like, bitwise logical operations or operations on integral operands or boolean operations. Javascript makes use of multiple assignment operators. Here we have listed JavaScript assignment operators for you.
