In this article, the editor introduces in detail "how to use go language to achieve string comparison". The content is detailed, the steps are clear, and the details are handled properly. I hope this article "how to use go language to achieve string comparison" can help you solve your doubts. Let's follow the editor's ideas to learn new knowledge.

Go language to compare strings: 1, use the "= =" operator, syntax "string 1" = string 2 "; 2, use the" strings.ToLower () "function; 3, use the" strings.Compare () "function; 4, use the" strings.EqualFold () "function.

Method 1: use the "=" operator (case sensitive)

Package mainimport "fmt" func main () {fmt.Println ("go" = = "go") fmt.Println ("GO" = = "go")}

Output:

Truefalse

Method 2: use strings.ToLower (case-insensitive)

Package mainimport ("fmt"strings") func main () {srcString: = "This a string" destString: = "this a string" if strings.ToLower (srcString) = = strings.ToLower (destString) {fmt.Println ("equal")} else {fmt.Println ("unequal")}}

Output:

Equal

Method 3: use strings.Compare (case sensitive)

Package mainimport ("fmt"strings") func main () {fmt.Println (strings.Compare ("GO", "go")) fmt.Println (strings.Compare ("go", "go"))}

Output:

-10

The Compare function, case-sensitive, is faster than the self-built method "=". Here are the comments

/ Compare is included only for symmetry with package bytes.

/ / It is usually clearer and always faster to use the built-in

/ / string comparison operators = =, and so on.

Func Compare (a, b string) int

Method 4: use strings.EqualFold (case-insensitive)

Package mainimport ("fmt"strings") func main () {fmt.Println (strings.EqualFold ("GO", "go")) fmt.Println (strings.EqualFold ("go", "go"))}

Output:
