Golang program to show promoted methods
In golang, Promoted methods are the methods created under those structs which are embedded inside another struct, now the struct in which it is embedded can access its methods and fields. In this article we are going to explain how to show promoted methods using various structs like Rectangle and Square, Vehicle and car. 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 Rectangle struct with two fields width and height of type float ...
Read MoreGolang program to depict use of promoted fields
In golang, promoted fields are the structs that are embedded inside another structs and their fields can also be accessed the structs in which they are embedded. In this article we are going to understand three different approaches to depict use of promoted filed with and without the help of pointers. Using Pointers In this illustration, we will make use of pointers to show the promoted fields. The field names will be set with the help of pointers and information will be printed using dot notation. Algorithm Step 1 − Create a package main and declare fmt(format package) package ...
Read MoreGolang program to show use of rand package
In golang, a rand package is used to generate random numbers/characters. Firstly, it seeds with the current time to get the different random Output each time then perform any operation. Syntax rand.Seed(value) Rand.Seed() function is used to generate random numbers. It takes a user input as argument which is the upper limit for generating random numbers. func Now() Time The Now() function is defined in time package. This function generates the current local time. To use this function, we have to first impot the time package in our program. func (t Time) UnixNano() int64 The UnixNano() function ...
Read MoreGolang program to print struct variables
In this Golang article, we will write programs to print struct variables. Here, there is no concept of classes, instead of that structs are used to represent a collection of related fields or properties. Using Name of the Field and Shorthand Declaration in the Main Function In this method, we will create a child struct and further create two fields name and age in it. The field values are set by creating the instance of the struct. In the second example, the field values of the Child struct are set in the instance using shorthand declaration and the field ...
