Go Count()

The Count() function returns the number of times a given substring appears in a given string without overlapping.

Syntax

strings.Count(str, sub)

Where str is the string being searched. sub, on the other hand, is the substring being searched for. It returns an int as the number of non-overlapping occurrences of sub in str. When sub is an empty string, Count() will count the boundaries before and after each character in str. (i.e. When str is “A” and sub is “”, Count() returns 2. When str is “ABC” and sub is “”, then Count() returns 4.)

Example

The following example searches for the letter “e” in “Codecademy” and prints out the result.

package main
import (
  "fmt"
  "strings"
)
func main() {
  name := "Codecademy"
  find := "e"
  fmt.Println(find, "is in", name, strings.Count(name,find), "times")
}
