Golang is a powerful programming language that offers a range of features and tools for building efficient and reliable applications. One such feature is the ability to define functions with multiple arguments. In this article, we will discuss how to use functions with two arguments in Golang and why this feature is useful. What are Functions with Two Arguments in Golang? In programming, a function is a set of instructions that performs a specific task. A function with two arguments, as the name suggests, is a function that takes two parameters or inputs. These inputs can be of any data ... Read More
Golang is a popular programming language that offers a range of features and tools for building efficient and reliable applications. One such feature is the ability to use functions as local variables. In this article, we will discuss how to use functions as local variables in Golang and why this feature is useful. What are Local Variables in Golang? Before we dive into how to use functions as local variables in Golang, let's first understand what local variables are. In programming, a local variable is a variable that is defined within a function or block of code. Local variables are ... Read More
Golang is a powerful programming language that has gained a lot of popularity in recent years. It offers many features and tools that make it easier for developers to create efficient and reliable applications. One of the features that sets Golang apart from other programming languages is the fallthrough keyword. In this article, we will take a look at how you can use the fallthrough keyword in your Golang programs. What is the Fallthrough Keyword in Golang? In Golang, the fallthrough keyword is used in switch statements to transfer control to the next case statement. When a case statement contains ... Read More
BMP180 sensor is a sensor that can be attached to a microcontroller on a breadboard and can measure the pressure, temperature, and altitude of a place. It can be connected to controllers such as ESP32 or Arduino and can be used by programs to read the values. In this article, using three different examples, the use of the BMP180 Sensor is demonstrated using ESP32. The circuit is made using an ESP32 microcontroller and BMP180 sensor and the programs to measure the temperature or pressure or altitude are written using Arduino software. Example 1 − Measuring the temperature of a place ... Read More
In Go, the switch statement can also be used with floating-point numbers. This feature can be useful in certain scenarios, where a floating-point value needs to be compared against different thresholds or ranges. In this article, we will go through an example program that demonstrates the use of switch statement on floating-point numbers. Syntax of Switch Statement with Float The syntax of switch statement with floating-point numbers is the same as that with any other type. The only difference is that the cases need to be specified as floating-point values. switch expression { case value1: ... Read More
In this article, using two different examples, the use of potentiometers is demonstrated using ESP32. In the first example, the trimmer type of potentiometer is used to vary the voltage between 0 and 3V. In the second example, the slider potentiometer is used on Wokwi Simulator to show the control of a servo motor. Wokwi simulator is software that can be used for running the code and virtually testing the results without buying the components. The actual diagram of the components is often different from those used in Wokwi, so the actual form of the slider potentiometer is given in ... Read More
Removing duplicates from a slice or an array is a common problem in programming. One of the ways to solve this problem in Golang is by using nested loops. In this article, we will write a Golang program that removes duplicates from a slice using nested loops. Understanding the Problem Before writing the program, let's understand the problem statement. Suppose we have a slice with some duplicate elements − numbers := []int{1, 2, 3, 1, 4, 2, 5} Our task is to remove the duplicate elements from this slice and get the unique elements. The final slice should look ... Read More
Golang allows us to use pointers to access the value of an object in memory. Using pointers can improve the performance of the code by reducing the memory allocation and enhancing the efficiency of the program. In this article, we will explore how to use a pointer to an array as a function argument in Golang. Pointer to an Array in Golang In Golang, an array is a fixed-length data structure that stores a collection of elements of the same type. When we pass an array to a function as an argument, a copy of the array is created, and ... Read More
In Golang, it is often required to split a slice of bytes after a specific separator. This can be done using the built-in function bytes.SplitAfter(). This function splits a slice of bytes into sub-slices after each occurrence of a specified separator. In this article, we will discuss how to split a slice of bytes after a specific separator in Golang. Syntax of bytes.SplitAfter() The syntax of the bytes.SplitAfter() function is − func SplitAfter(s, sep []byte) [][]byte where s is the slice of bytes to be split, and sep is the separator. Example package main import ( ... Read More
Slices are an essential feature of Go programming language that allows you to store and manipulate an ordered collection of elements. Slices are similar to arrays, but unlike arrays, they are dynamic and can be resized. In Go, you can perform a search operation on a slice to find an element or a set of elements. This article will guide you through the process of searching for an element of int type in a slice of ints in Go. Searching an element of int type in slice of ints in Golang To search for an element of int type in ... Read More
