create a mutable variable of type int in go

To create a mutable variable of type int in Go, you can use the following syntax to declare and initialize it:

main.go
var myVariable int = 42
24 chars
2 lines

This creates a variable named myVariable of type int, which is initialized with the integer value 42.

If you don't want to specify an initial value, you can leave out the value and let Go initialize the variable to its default value:

main.go
var myVariable int
19 chars
2 lines

This creates a variable named myVariable of type int, which is initialized to its default value of 0.

Once a variable is declared, you can modify its value simply by assigning a new value to it, like this:

main.go
myVariable = 10
16 chars
2 lines

This changes the value of myVariable from 42 to 10. Since the variable is mutable, you can assign new values to it as many times as you want.
