Overview of Go lang

Go is a Open source programming language that makes it easy to build simple, reliable and efficient software. History of Go lang The Go programming language is initially started in 2007 as an internal Google project.The original designed by Robert Griesemer, Rob Pike and Ken Thomson.November 2009, Go is publicly released under the open source license.Go has an open source model and many developers over the world contribute to it with the original designers.  Overview of Go langGo is often referred to as "Simple" programming language, a language that can be learned in a few hours if you already know another language C / C++.Go language was designed to feel familiar and to stay as simple as possible.Go language is created System programming in mind, even go can be used to create a web application using Google's App Engine. Why Go lang 1) Efficient use of 21st-century computers Computers have evolved, but programming language doesn't have the same pace of evolution. Tod…

Arrays in C Language

Image
Suppose you want to store the 10 numbers. The one choice is to create a 10 different variable but it is difficult when number of variable are increases. So the next solution that is more feasible is array. An array is the collection of various similar type elements stored in contiguous memory locations. All the array elements share the common name. To uniquely identify each element an index or subscript is associated with the element. so the array is also known as subscript variable. In the given figure arrangement of array elements are shown. The address of the first element is 100. If the given array is of type integer and integer occupies 2 bytes then the next element in the array has address 102,104 etc as given in the figure. How to access array elements using subscript operator it is also shown in the given figure.Array index always start with 0. To access array element subscript operator is used.[] is called subscript operator.a[0] read a of 0 or 0th element of aCreating/Declar…

Data Types in Go language

Image
Data type defines a set of related values, describe the operations that can be done on them and define the way the stored in memory.  For example: Suppose you have a Car of VW Polo, but a car can be of any other company with some other basic and some advanced features.
But if we called a name Car, then in your mind a picture is created that there is a vehicle with 4-wheels and steering. Each car has some features like the color, company, make, model etc.

Types in programming work in a similar way, For example, "Hello World" is a string and every string have some length.

Numbers Go Comes with different types to represent numbers, Numbers can be categorized into two broad categories...
Integer The integer represents only those numbers which don't include any decimal places and can be of any positive and negative numbers. Example : {1, 3, -4, 11, 123, 534} all are integer numbers
Go's integer type can be uint8, uint16, uint32, uint64, int8, int16, int32, and int64. 8, 1…

Creating your first html page

Image
HTML page structure As we have already discussed, every HTML page is divided into two section -:Head SectionBody SectionHead sectionThis is a section which is actually not visible to the users on the web page, but it helps the content how to display the content.It is used to write the title, meta, script, style etc.Body SectionThis is a section which is actually visible on the web page. Example-1 <!doctype html> <html>           <head>                       <title>My First Web page</title>           </head>          <body>                      Welcome!!! in the world of web.           </body>   </html> Example Explained: 
 <!doctype html> reprents, which html version you are using. For html-5 doctype is as written. Before html-5 doctype is too complicatd. HTML-5 simplified doctype.Every HTML page starts with <html></html> tag.Because each HTML page have head section and body section, which is represented by <hea…

Say Hello world in Go lang

Image
Writing your first program "Hello World" package main
import "fmt"
func main( ) {
       fmt.Print("Hello World")
} Understanding the program line by line As we have discussed in the overview of go lang that Go program is organized in the various package. Here first statement package main specifies that this program will belong to the package main.Next line import "fmt" includes the predefined package fmt in your program so that you can use the functions (features) of this package in your program. Here import is the keyword in go lang use to import package(s).fmt stands for the format, fmt package has the various pre-defined function like Print, Println, Printf to print the formatted text and other methods like Scanf for reading the formatted values.Next Line defines the main() function, which is the starting point of every program. func is a keyword in go lang to define a function.Within the main() function we have written fmt.Print("Hello…

On WindowsDownload the latest version of go MSI installer from https://golang.org/dl/ best suited for your system architecture.Start the installation by double-clicking on the installer and installer wizard will open as given in the following figure. For the installation follow the wizard instructions.Note that when you installing go lang using installer then it will ask the location where go will be installed as shown in the figure below. Installation directory of go lang is called GOROOT here the GOROOT is c:\go directory.After this follow the wizard instructions and complete the go lang installation. Test Go installation To Check that Go is installed correctly or not, you need to create a go workspace (a place /folder/directory in which you save you go programs) and create a sample go program and run the program using the command line. The sample program is given below...You can create a sample program by using any simple text editor like notepad, notepad++, sublime or anyone you lik…

Arrays in Go lang

Image
What is ArrayAn array is the collection of similar type of elements.An array is the collection of fixed length.Array elements are stored in contiguous memory locations.All the array elements share the common name, but each element is uniquely identified their index or subscript, so the array is also called a subscript variable.Array index always starts with 0. Creating an array var arr [5]int Note: In the above program snippet, arr is an array of 5 integers.By default, all the array elements are initialized with a default value. Default ValuesData TypeDefault ValueInt(s)0Float(s)0.0bool(s)falseObjectsnil
Note: Following example demonstrate the default values for array elements.
Example-1 package main
import "fmt"
func main() {
var arr1 [5]int
var arr2 [5]float32
var arr3 [5]string
var arr4 [5]bool
fmt.Println(arr1)
fmt.Println(arr2)
fmt.Printf(arr3)
fmt.Println(arr4)
} Output  [0 0 0 0 0] [0 0 0 0 0] [    ] [false false false false false] Example-2 package main

String in golang

Image
Strings are sequence of characters with definite length and can be created by enclosing in double quotes "Hello Go" and back ticks `Hello Go`. A string is a sequence of characters.Strings are the collection of individual bytes, where each character occupy single byte.Characters out of the ASCII characters (can say characters from other languages) occupy more than one byte.A string can be created by enclosing in double quotes "Hello Go" or backticks `Hello Go`.The difference between double quotes and backticks is that double quotes allow escape sequences like \n (newline) and \t (tab) and parses them but backticks don't. Example-1: package main
import "fmt"
func main( ) {
        fmt.Println(len("Hello Go"))
        fmt.Println("Hello Go"[1])
        fmt.Println("Hello"+" "+"Go")
} Output: 8101Hello Go 
 Output Explained:

fmt.Println(len("Hello Go")) returns the length of the string "Hell…

Decision Making in Go lang

Image
Introduction to decision making Sometimes we need to introduce a power in our program, that our program should automatically make the decision.

For example:  if the temperature of the day is more than 20 degree then it's hot otherwise it's cool.

To introduce this kind of power in our program, we use decision making statements as the list below...
if-else statementsnested if-else statementselse-if ladderswitch/case-control statement Let's create a program to check whether a number is even or odd. Program to check a number is even or odd in Go lang. package main
import "fmt"
func main() {
var n int32
fmt.Print("Enter any number:")
fmt.Scan(&n)
if n % 2 == 0 {
fmt.Println(n,"is even")
} else {
fmt.Println(n,"is odd")
}
} Output: Enter any number:55
55 is odd  Explanation:A number is even if it is divisible by 2 otherwise odd.So to check a number is even or odd, we need to check divisibility by 2.To perform the divisibility test we use mod (%…

Decision Making Statements

As in the real world we need to make decision according to the situation. In the same sense we need to make decision while creating program.For decision making C provides various construct as follows:if statementif else statementnested if else statementelse if Laddercondional operatorswitch/case constructBy using the above-given decision-making statement we can implement the sense in a program that program can create decision automatically.if-else statementSyntax-1if(condition) { statement1; statement2; statement3; ........ ........ } else { statement1; statement2; statement3; ........ ........ } Syntax-2if(condition) statement; else statement; Syntax ExplainedThe block which is specified with if is called if-block and the block with else is called else block. If there is a single statement in if block or else block then no need to enclose in {} (curly braces). But in the case of more than one statement and if a…
