Go Language Tutorial
In Go programming, len function is used to find the length of the string.
length will be return as integer data type when using len function.
package main import "fmt" func main() { var str string Var length int str = "codingpointer.com!" length = len(str) fmt.Printf("String Length '%s': %d\n", str, length) }Output:
$ go build string-length.go $ ./string-length String Length 'codingpointer.com!': 18
length variable does not required to be declared before assigning len function result. We can also := to assign length as integer.
package main import "fmt" func main() { var str string str = "codingpointer.com!" length := len(str) fmt.Printf("String Length '%s': %d\n", str, length) }Output:
$ go build string-length.go $ ./string-length String Length 'codingpointer.com!': 18« Previous Next »
