I need to read [100]byte to transfer a bunch of string data.
Because not all of the strings are precisely 100 characters long, the remaining part of the byte array is padded with 0s.
If I convert [100]byte to string by: string(byteArray[:]), the tailing 0s are displayed as ^@^@s.
In C, the string will terminate upon 0, so what's the best way to convert this byte array to string in Go?

Given a Byte value in Java, the task is to convert this byte value to string type. One method is to create a string variable and then append the byte value to the string variable with the help of + operator. This will directly convert the byte value to a string and add it in the string variable.
There are two ways to convert byte array to String: By using String class constructor. By using UTF-8 encoding.
In order to convert a byte array to a file, we will be using a method named the getBytes() method of String class. Implementation: Convert a String into a byte array and write it in a file. Example: Java.
Methods that read data into byte slices return the number of bytes read. You should save that number and then use it to create your string. If n is the number of bytes read, your code would look like this:
s := string(byteArray[:n]) To convert the full string, this can be used:
s := string(byteArray[:len(byteArray)]) This is equivalent to:
s := string(byteArray[:]) If for some reason you don't know n, you could use the bytes package to find it, assuming your input doesn't have a null character embedded in it.
n := bytes.Index(byteArray[:], []byte{0}) Or as icza pointed out, you can use the code below:
n := bytes.IndexByte(byteArray[:], 0) Use:
s := string(byteArray[:]) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
