I tried debugging and I see that every 4th element in the char array is Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. Trouble is, it's interpreting the uint8s as chars and it outputs a string rather than an array of numbers. In Hey guys I have trouble converting this statement below in C to Golang. In this post, we will go into detail about type-casting in the Go programming language. The language supports converting both of these types ([]byte 5 The conversion s := string(stuff) is fine, but usually you'd expect stuff to contain actual printable character sequences. Println("The amount is: " + strconv. How can I do that? strconv. Here is my attempt using an ostringstream, but the string seems to be empty afterward. Sprintf, fmt. In Go, you can convert a byte array to a string using the `string ()` function. However, when you start to program, the frequent interconversions between each of them can be confusing. When I pass in a []uint8, if gives me Overview In this tutorial, we will see how to convert an array of ints or numbers to a string in Go. I noticed when I cast a rune/int8 array to The basic types in Go are as follows: bool — Boolean values: true or false string — Strings int, int8, int16, int32, int64 — Signed integer types uint, uint8, uint16, uint32, uint64, uintptr — unsupported Scan, storing driver.
