Strings vs Numbers in Go

• Go distinguishes between numbers and strings.

  
  

• 15 is a number. "15" is a string because it is surrounded by quotes.

  
  

• We can do math with numbers, but not with strings that only look like numbers.

Full lesson:

Types tell Go what kind of value we are working with.

var age int = 29
var phone string = "2025550153"

age is a number, so it has type int. phone is text, so it has type string, even though it contains digits.

Assignment
Follow the Coding Tutorial and make age a number and phone a string.

Hint
Numbers do not use quotes. Strings use quotes.
