Golang program to return the values from the block
In this golang article, we will learn how to return the values from the block using external function, an anonymous function. A block is created using curly braces where the scope of variables remains inside the block and not outside of it. Example 1 In this Example, two values of x and y are added in the code block and z will be assigned the added value. Then, call the function getResult in which another x and y are added and assigned to z in the code block. package main import "fmt" func main() { ...
Read MoreGolang program to convert milliseconds to minutes and seconds
In this golang article, we will write Go language programs to convert milliseconds to minutes and seconds using various methods. Milliseconds are converted to minutes and seconds mathematically using different set of logics. Algorithm Step 1 − Import the required packages in the program Step 2 − Create a main function Step 3 − In the main take milliseconds value and convert it into minutes and seconds using different logics mathematically Step 4 − Then, print the output using Printf function from the fmt package Example 1 In this Example, we will take the milliseconds value. Then, the ...
Read MoreGolang program to create multiple BEGIN and END blocks
In this article, we will learn to write Go language programs that will create multiple BEGIN and END blocks using curly braces, “conditional statements”, as well as “external functions”. A block is created using curly braces, the scope of a variable remains inside the block and not outside it. Algorithm Step 1 − Create a package main and declare fmt(format package) package in the program where main produces executable codes and fmt helps in formatting input and output. Step 2 − Create a main function Step 3 − In the main, create a first block by initializing ...
Read MoreGolang program to demonstrate BEGIN and END blocks
In this Go language article, we will write programs to demonstrate BEGIN and END blocks using sum of numbers, iteration and two variables. Blocks are used to group the statements where the variables described in the block can only be used in that scope and not outside it. They also help in code readability Algorithm Step 1 − Create a package main and declare fmt(format package) package in the program where main produces executable codes and fmt helps in formatting input and output. Step 2 − Create a main function and in this function create two begin and end ...
Read MoreGolang program to format time in AM-PM format
In Go language article, we will write programs to format time in AM-PM format using now and format package, as well as using now and format function with minutes and seconds. The current time can be obtained using Now function from the time package whereas we can format the time using Format function as we are going to use in this article. In this article we will use “now and format function” to get the formatted time in AM-PM format. Syntax funcNow() Time The Now() function is defined in time package. This function generates the current local time. To ...
Read MoreGolang program to get the hash elements as a sorted array from the hash collection
In golang we can obtain the hash elements as a sorted array from the hash collection using iteration, sort package as well as slice function. A hash collection contains a hashmap which is used to store items in the form of key value pairs. A hashmap is implemented using a hash function. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments func append(slice, element_1, element_2…, element_N) []T The append function is used to ...
Read MoreGolang program to replace the items of hash collection from another hash collection
In this Go language article, we learn how to replace the items of hash collection from another hash collection using ok idiom method as well as a loop to replace the items of hash collection. A hash collection contains a hashmap which is an efficient data structure Syntax func range(variable) The range function is used to iterate over any data type. To use this, we first have to write the range keyword followed by the data type to which we want to iterate and as a result the loop will iterate till the last element of the variable. Algorithm ...
Read MoreGolang program to delete the item from the hash collection based on a specific key
In this article, we will learn how tp write a Go language programs to delete the item from the hash collection based on a specified key using ok idiom method and delete keyword A hash map is a part of the hash collection. It stores the data as key value pairs which helps in the efficient execution of the program. Algorithm Step 1 − This program imports two packages fmt and main where fmt helps in the formatting of input and output and main helps in generating executable codes Step 2 − Create a main function Step 3 ...
Read MoreGolang program to get value from the hash collection based on specified key
In this golang article, we will write Go language programs to get the value from the hash collection based on a specified key using found variable as well as using ok idiom method. A hash map is a data structure that belongs to the hash collection. It stores the data in the form of key value pairs. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments. Algorithm Step 1 − This program imports ...
Read MoreGolang Program to Find the current working directory
In go language we can use the functions present in os package like Getwd() and Args to find the current directory in which our code is getting executed. The directory from which the program is currently being run is called the current directory. It is also known as present working directory. The directory in which the program is currently running is called the working directory. It is the parent directory for any files or the or directory that are created during runtime. Algorithm First, we need to import the "fmt" and "os" packages. Then, start the main() function. Inside ...
