In this tutorial, we will learn how to print diamond star pattern using Go programming language. Syntax for initialization; condition; update { statement(s) } Example: Golang Program Code To Print Diamond Star Pattern Using A Single Function Algorithm Step 1 − Import the package fmt. Step 2 − Start the function main (). Step 3 − Declare and initialize the variables. Step 4 − Use of for loop with condition and incrementor. Step 5 − Print the result using fmt.Println (). Example // GOLANG PROGRAM TO PRINT DIAMOND STAR PATTERN package main // ... Read More

In this tutorial, we will learn how to print 8−star pattern using Go programming language. Syntax for initialization; condition; update { statement(s) } Example: Golang Program Code To Print 8 Star Pattern Using A Single Function Algorithm Step 1 − Import the package fmt. Step 2 − Start the function main (). Step 3 − Declare and initialize the variable. Step 4 − Use of for loop with condition and incrementor. Step 5 − Print the result using fmt.Printf (). Example // GOLANG PROGRAM TO PRINT 8 STAR PATTERN package main // fmt ... Read More

In this article we will discuss about how to get the successor of an integer number using library function in Go language. The successor of an integer number is defined as the number that comes after it. For example the successor of 2 is 2 + 1 = 3. Similarly, successor of −50 is −49 and so on. Syntax Syntax for Println() = fmt.Println(...interface{}) Example 1: We Will Get The Successor Of The Integer Number Using Library Function In A Single Function Algorithm Step 1 − Import the package fmt. Step 2 − Start the function main (). Step 3 ... Read More

In this article we will discuss about how to get the predecessor of an integer number using library function in Go language. The predecessor of an integer number is defined as the number that comes before it. For example the predecessor of 2 is 2 – 1 = 1. Similarly, predecessor of -50 is -51 and so on. Syntax Syntax for Println() = fmt.Println(...interface{}) Example 1: We Will Get The Predecessor of the integer number using Library Function Algorithm Step 1 − Import the package fmt. Step 2 − Start function main function(). Step 3 − Initialize a ... Read More

In this tutorial, we will learn how to create pyramids with different patterns in Go programming languageSyntax NESTED FOR LOOP for [condition | ( init; condition; increment ) | Range] { for [condition | ( init; condition; increment ) | Range] { statement(s); } statement(s); } Example 1: Golang code to Create Pyramid And Pattern Using $ Algorithm Step 1 − Import the package fmt. Step 2 − Start function main (). Step 3 − Declare and initialize the variables. Step 4 − ... Read More

In the tutorial, we learn how to convert numeric data to hexadecimal number using Go programming language. The hexadecimal number system is described as a 16-digit number representation of numbers from 0 - 9 and digits from A - F. In other words, the first 9 numbers or digits are represented as numbers while the next 6 digits are represented as symbols from A - F. Example 1: Golang Program Code to Convert Data to Hexadecimal Number Using fmt.Sprintf() Function Syntax func Sprintf(format string, a ...interface{}) string The fmt.Sprintf() function in Go language formats according to a format specifier ...

In this tutorial, we will learn how to check for palindrome in Go programming language. We will check for palindrome for both numbers and strings in separate examples. A palindrome is a word, number, phrase, or other sequence of symbols that reads the same backwards as forwards, such as the words civic or radar or numbers such as 22\2\22 or sentence such as “Mr. Owl ate my metal worm”. Example 1: Golang Program code to Show if a Number is palindrome using a Single Function Syntax Syntax of For loop Initialize for condition { } incrementor The initialization statement ... Read More

In this tutorial, we will learn how to check if given two strings are anagrams of each other or not using Go programming language. A word or phrase formed by rearranging the letters of a different word or phrase by using all the letters exactly once is known as an anagram. Example − Roles anagram word is loser Binary anagram word is brainy The below example shows how to create an empty map using the built-in make () function. The make function allocates and initializes a hash map data structure and returns a map value that points to it. The specifics ... Read More

In this tutorial, we will learn how to check if a given string is numeric or not using Go programming language. We will be using the regexp package in Go to validate the numeric patterning of the string. Examples of numeric string − A string which has a numeric value in it T20CRICKET GOOD1 100PERCENT Syntax func MustCompile(str string) *Regexp //This function creates the regular expression func MatchString(pattern string, s string) (matched bool, err error) // This function returns a Boolean value that indicates whether a pattern is matched by the string Example 1: Golang Program Code ...

In this tutorial, we will learn how to check for Armstrong number in Go programming language. An Armstrong number or the narcissist number is a number whose sum of digits raised to the power three equals the number itself. Example1: $\mathrm{(1^3) \:+ \:(5^3) \:+ \:(3^3)\:= \:153}$ Example2: $\mathrm{(3^3) \:+ \:(7^3) \:+ \:(1^3)\:= \:371}$ In the below examples, we will read an integer number and then check the given number is an Armstrong number using Golang program Syntax Syntax of For loop Initialize for condition { } incrementor The initialization statement is optional and executes before for ...
