Golang program to demonstrate the argument passing to block
In this article, we are going to learn how to demonstrate the argument to block using the user-defined function, iterations, and square of numbers . A block is created using curly braces with a definite begin and end braces. The different operations are performed inside the braces. Algorithm Step 1 − Import the required packages in the program Step 2 − Create a main function and in there create a slice Step 3 − Use a function to pass the argument and print the values with the help of iteration Step 4 − Print statement is executed ...
Read MoreGolang program to get the current day of the year out of 365
In Golang we can use functions like YearDay and Sub as well as arithmetic operation method to get the current day of the year out of 365. The current time is obtained using the Now function from the time package and YearDay() function is used to obtain the current day of the year out of 365. Method 1: Using YearDay and Sub Functions In this method, the number of days between the current date and start of the year are calculated using currentTime.Sub(start_of_year).Hours() / 24 as well as simple YearDay method. Syntax func Now() Time The Now() function ...
Read MoreGolang program to add two dates
In this Golang article, we will write programs to add two dates. The dates are added using methods like Add(), AddDate(). There are different formats to represent a date. Here, the dates after addition will be represented using YY/MM/DD format. Syntax func (t Time) Sub(u Time) Duration The sub() function in Go is used to get the difference between two dates. In this function the first two parameters i.e., t and u are date values and this function returns the difference between two values in hours, minutes and seconds. time.Parse() This function belongs to the time package. It ...
Read MoreHow To Access Different Rows Of A Multidimensional Numpy Array?
NumPy Multidimensional Arrays As the name suggests, Multidimensional Arrays are a technique that can be described as a way of defining and storing data in a format that has more than two dimensions (2D). Python allows the implementation of Multidimensional Arrays by nesting a list function inside another list function. Here are some examples on how we can create single and multidimensional arrays in Python using Numpy. Single Dimensional Array Example import numpy as np simple_arr = np.array([0, 1, 2, 3, 4]) print(simple_arr ) Output [0 1 2 3 4] Algorithm Import the NumPy library Use ...
Read MoreHaskell Program to Convert String value to byte Value
In Haskell, we will convert String Value to Byte value by using ord , B.pack and fromNum functions. In the first example, we are going to use (stringToBytes = map ord ) function and in the second example, we are going to call (stringToBytes = B.pack) function. And in the third example, we are going to use (byteList = map fromEnum str) function. Algorithm Step 1 − The Data.Char module is imported. Step 2 − The stringToBytes function is defined using ord function as, Step 3 − The program execution will be started from main function. The main() function ...
Read MoreHaskell Program to Convert List to a Map
In Haskell, we will convert List to a Map by using fromList and foldl functions. This can also be done using recursion and pattern matching. In the first example, we are going to use (listToMap xs = Map.fromList xs) function and in the second example, we are going to use (listToMap xs = List.foldl' (\acc (k, v) -> Map.insert k v acc) Map.empty xs) function. In the third example, we are going to use base and recursive case of the recursive function. Algorithm Step 1 − The qualified Data.Map module is imported. Step 2 − The listToMap function is ...
Read MoreHaskell Program to Convert String to an Array
In Haskell, we will convert String to an Array by using listArray and intersperse functions. In the first example, we are going to use (stringToArray s = listArray (0, length s - 1) s) function and in the second example, we are going to use (stringToArray s = s) function. In the third example, we are going to use (stringToArray s = intersperse ' ' s). Algorithm Step 1 − The stringToArray function is defined Step 2 − The program execution will be started from main function. The main() function has whole control of the program. It is written ...
Read MoreHaskell Program to Convert Character to String
In Haskell, we can convert Character to String by using user-defined function, show function, list comprehension and (:[]) notation. In the first example, we are going to use (charToString c = [c]) function and in the second example, we are going to use (charToString c = show c) function. Where as in third, we are going to use (charToString c = [x | x String charToString c = [c] main :: IO () main = do let myChar = 'a' let myString = charToString myChar putStrLn myString Output [1 of 1] ...
Read MoreHaskell Program to Check Whether an Alphabet is Vowel or Consonant
We can use elem function in Haskell to check whether the given alphabet is vowel or consonant. In the first example, we are going to use (isVowel c = c `elem` "aeiouAEIOU") function. And in other examples, we’re going to use elem function along with certain if-else statements, nested conditions and guards. Algorithm Step 1 − The data type ‘Person’ is defined with two fields name and an age. Step 2 − The isVowel function is defined using elem function as Step 3 − The program execution will be started from main function. The main() function has whole control ...
Read MoreHaskell Program to Call One Constructor from Another
In Haskell, we will call one constructor from another by using user-defined function. In the first example, we are going to use (newPerson name = Person name 10) constructor and in the second example, we are going to use (newPerson n a = Person { name = n, age = a }) constructor. In the third example, we are going to use (clonePerson p = p { name = name p ++ " clone" }) constructor and in the fourth example, we are going to use (clonePerson p = p { name = name p ++ " clone" }) ...
