convert int to ascii – more than one character in rune literal

Issue

How do I convert into to its ASCII?

In java it’s System.out.println((char)(49)); //gives 1

I tried

a := '42'
fmt.Println(rune(a))

I get more than one character in rune literal

Solution

The reason you’re getting this error is in this variable:

a := '42'

A byte literal may only contain one character, use this instead;

a := byte(42)

Edit:
Use string(a) to get the expected results, like boo said.
