Golang Program to pad a string with 0's on left side
In the Go programming language, strings are a built-in data type that represents sequences of characters. They are defined using double quotes (") and can contain any valid Unicode characters. In this article, we are going to learn different techniques to pad a string with 0’s on the left side. Method 1: Using User-defined function In this method, we will achieve this by creating an external function. The function accepts the string to be padded along with the length as argument and returns the final string after adding zeroes to left of it. Algorithm Step 1 − First, we ...
Read MoreGolang Program to get the index of the substring in a string
In the Go programming language, strings are a built-in data type that represents sequences of characters. They are defined using double quotes (") and can contain any valid Unicode characters. A substring is a portion of a string that contains a sequence of characters from the original string. A substring can be obtained in Go by using the slicing syntax on a string value. In this article we are going to learn different methods to get the index of a substring in a string using golang programming. Method 1: Using a For Loop In this method, the function that we ...
Read MoreGolang Program to merge two integer arrays without using library function
An array in go language is defined as the data structure that is used to store elements in contiguous memory locations. Arrays allow us to search and store elements at constant time. arrays use index to store elements which starts from 0 and goes to n – 1, where n is the length of the array. Here we will use two methods in the first method we will implement the logic in the main section of the program while in the second one we will use an external function. Method 1:Using For Loops In The Main Here we will use ...
Read MoreGolang Program to convert int type variables to long
In go language a long type variable is not a separate data type but it is an extension made from the integer data type to store even larger types of integers. The main difference between an int data type and long data type is that int data type is 32 bits whereas long data type is 64 bits. Syntax func typeOf (x interface{}) The typeOf() function is used to get the type of any variable. This function is present in reflect package and it takes the variable whose type is to be determined as an argument. The function then ...
Read MoreGolang Program to cyclically permutes the elements of the array
Cyclically means that in every cycle we wish to move the array elements by one position till we get the original array again. Cyclic permutation can be useful in various matrix manipulation and linear algebra operations. In this article, we are going to see different examples to permute the elements of the array cyclically using go programming language. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to an array slice. It takes number of arguments. The first argument is the array to which we wish to add the values followed by the ...
Read MoreGolang Program to check a given number is finite or not
In this article we will write a go language program to check if a given number is finite or not. The program uses IsInf() and IsNaN() library functions in order to check whether numbers are finite or not. Syntax func IsInf(f float64, sign int) bool IsInf() function is present in the math package. This function takes two arguments one is the floating point number that we wish to check and the other is the sign. The sign is an integer which can be greater than, lesser than, or equal to zero. If the sign is greater than zero then ...
Read MoreGolang Program to delete an item from the array without using the library function
An array in go language is defined as the data structure that is used to store elements in contiguous memory locations. Arrays allow us to search and store elements at constant time. arrays use index to store elements which starts from 0 and goes to n – 1, where n is the length of the array. Method 1: Using An External User-Defined Function The following method, illustrates how we can remove a particular integer element from the array of integers using an external function. Algorithm Step 1 − Import the fmt package. Step 2 − Defining a function named ...
Read MoreGolang Program to calculate the sum of columns of matrix elements
A matrix is a collection of numbers arranged in rows and columns, a two-dimensional array, each of the values of this matrix is known as an element. Here we will use three methods to find the sum of column elements and compare each method for the same using go programming. Here is an example of a matrix and the sum value of it’s columns − The given matrix is − 0 1 2 4 5 6 8 9 7 Sum of elements in column 1 is 12 Sum of elements in column 2 ...
Read MoreGolang Program to calculate the sum of rows of matrix elements
A matrix is a collection of numbers arranged in rows and columns, a two-dimensional array. Here we will use three methods to find the sum of elements and compare each method for the same using Go Programming language. Algorithm Step 1 − Import the fmt package. Step 2 − Now we need to start the main() function. Step 3 − Then we are creating a matrix naming matrix. Step 4 − Print the matrix on the screen using fmt.Println() function. Step 5 − Initialize a new variable called sum of type int to hold the resultant sum. Step ...
Read MoreGolang Program to Determine the class of an object
What are Objects in Golang? Objects are defined on the structs and store Key-value pairs of data together in go programming. There are numerous methods for producing an object. A struct is a user-defined type that groups together a collection of fields (also known as properties or data members) and methods. A struct can be defined using the type keyword, followed by the struct name and a struct literal that defines the fields of the struct. Method 1: Using a user-defined function Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Then we ...
