Go Compare()

The strings.Compare() function is a built-in function in Golang that compares two strings lexicographically. It returns an integer value that indicates the relationship between the two strings.

Syntax

strings.Compare(str1, str2)

Where str1 and str2 are the two strings to be compared:

• If the two strings are equal, the function returns 0.
• If the first string is lexicographically less than the second string, the function returns a negative value.
• If the first string is lexicographically greater than the second string, the function returns a positive value.

Example

The following example demonstrates the use of the strings.Compare() function.

package main

import (
  "fmt"
  "strings"
)

func main() {
  greater := strings.Compare("Z", "A")
  equal := strings.Compare("W", "W")
  lesser := strings.Compare("A", "Z")

  fmt.Println(greater)
  fmt.Println(equal)
  fmt.Println(lesser)
}
