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 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 .
