str1 := bytes.NewBuffer(byteArray).String() fmt.Println("String =",str1) } Output: String = HELLO 3. Using fmt.Sprintf() function to convert byte array to string This is a workaround way to convert byte array to string. The Sprintf() function is a bit slow but we can use it ...
Problem: Each time converting a bytes to string involves a memory allocation, caused by the design immutable string and mutable bytes. Investigation: Logically, a constant string which embedded into binaries got limited usage. And the de...
In the code example, we convert the file_size variable, which has type int64, to a string with strconv.FormatInt. $ go run int2str2.go The file size is 1544466212 bytes Go int to string with fmt.SprintfAnother way to convert an integer to a string is to use the fmt.Sprintf function...
