To check two strings in Go, you need to use the comparability operators ==, !=, >=, <=, <, >. Alternatively, you need to use the strings.Evaluate() operate from the strings package deal.
When evaluating strings, we imply lexicographic (alphabetical) order.
Comparability operators
Strings in Go help comparability operators ==, !=, >=, <=, <, > to match strings in lexicographic (alphabetical) order. The results of the comparability is a bool worth (true or false) indicating if the situation is met.
Instance:
package deal predominant
import "fmt"
func predominant() {
str1 := "gosamples"
str2 := "dev"
str3 := "gosamples"
fmt.Printf("%s == %s: %tn", str1, str2, str1 == str2)
fmt.Printf("%s == %s: %tn", str1, str3, str1 == str3)
fmt.Printf("%s != %s: %tn", str1, str2, str1 != str2)
fmt.Printf("%s != %s: %tnn", str1, str3, str1 != str3)
fmt.Printf("%s >= %s: %tn", str1, str2, str1 >= str2)
fmt.Printf("%s >= %s: %tn", str1, str3, str1 >= str3)
fmt.Printf("%s > %s: %tn", str1, str2, str1 > str2)
fmt.Printf("%s > %s: %tnn", str1, str3, str1 > str3)
fmt.Printf("%s <= %s: %tn", str1, str2, str1 <= str2)
fmt.Printf("%s <= %s: %tn", str1, str3, str1 <= str3)
fmt.Printf("%s < %s: %tn", str1, str2, str1 < str2)
fmt.Printf("%s < %s: %tn", str1, str3, str1 < str3)
}
Output:
gosamples == dev: false
gosamples == gosamples: true
gosamples != dev: true
gosamples != gosamples: false
gosamples >= dev: true
gosamples >= gosamples: true
gosamples > dev: true
gosamples > gosamples: false
gosamples <= dev: false
gosamples <= gosamples: true
gosamples < dev: false
gosamples < gosamples: false
The strings.Evaluate() operate compares two strings in lexicographic order returning an int worth in consequence:
The result’s:
0ifa == b1ifa > b-1ifa < b
Instance:
package deal predominant
import (
"fmt"
"strings"
)
func predominant() {
str1 := "gosamples"
str2 := "dev"
str3 := "gosamples"
fmt.Printf("strings.Evaluate(%s, %s): %dn", str1, str2, strings.Evaluate(str1, str2))
fmt.Printf("strings.Evaluate(%s, %s): %dn", str1, str3, strings.Evaluate(str1, str3))
fmt.Printf("strings.Evaluate(%s, %s): %dn", str2, str1, strings.Evaluate(str2, str1))
}
Output:
strings.Evaluate(gosamples, dev): 1
strings.Evaluate(gosamples, gosamples): 0
strings.Evaluate(dev, gosamples): -1
Case-insensitive string comparability
If you wish to evaluate whether or not two strings are equal with out taking note of the case, you possibly can carry out a case-insensitive string comparability. Try easy methods to do it in our different tutorial.
