What is Strconv Atoi?
Atoi() The Atoi() function is an inbuilt function of the strconv package which is used to convert (interpret) a given string s in the given base (10) and bit size (0) and returns the corresponding integer value. The Atoi() function is equivalent to ParseInt(s, 10, 0), converted to type int.
What is Strconv in Golang?
Go language provides a strconv package that implements conversions to and from string representations of basic data types. To access the functions of the strconv package you need to import the strconv package in your program with the help of the import keyword. Function.
What is Strconv ITOA Golang?
Go language provides inbuilt support to implement conversions to and from string representations of basic data types by strconv Package. This package provides an Itoa() function which is equivalent to FormatInt(int64(x), 10). Or in other words, Itoa() function returns the string representation of x when the base is 10.
What is Rune in Golang?

What is an enum in go?
An enum is a data type consisting of a set of named constant values. Enums are a powerful feature with a wide range of uses. However, in Golang, they’re implemented quite differently than most other programming languages. Golang does not support enums directly. We can implement it using iota and constants .
