When you define variables that overlap in the marker address area, in this example a string and an array of bytes, it is like a union in C. You can put a string into the string variable and then each character can be pulled out from the overlapping byte array. In the program, I onl...
arr: array of Byte; i: integer; s2: string; begin //string to byte array SetLength(arr,Length(s)); CopyMemory(arr,PChar(s),Length(s)); for i := 0 to High(arr) - 1 do ShowMessage(chr(arr[i])); //byte array to string SetLength(s2,Length(arr)); CopyMemory(PChar(s2),arr,...
Convert a string to a ByteArray of its UTF-8 representation: In[1]:= Out[1]= Convert the bytes to a list of numbers: In[2]:= Out[2]= Convert a string to a ByteArray of its ISO 8859-7 Latin/Greek representation: In[1]:= Out[1]= Convert the bytes to a list of num...
String class also has a method to convert a subset of the byte array to String. byte[] byteArray1 = { 80, 65, 78, 75, 65, 74 }; String str = new String(byteArray1, 0, 3, StandardCharsets.UTF_8); Above code is perfectly fine and ‘str’ value will be ‘PAN’. That’s a...

🔔上图中可以看出 stringStruct和slice还是有一些相似之处,str和array指针指向底层数组的地址,len代表的就是数组长度。 关于string类型,在go标准库中官方说明如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 // string is the set of all strings of 8-bit bytes, conventionally but not// necessaril...
* Constructs a new {@codeString} by decoding the specified array of bytes * using the specified {@linkplainjava.nio.charset.Charset charset}. The * length of the new {@codeString} is a function of the charset, and hence * may not be equal to the length of the byte array. ...
Input: ARRAY [1..255] OF BYTE = 72, 69, 76, 76, 79;Order: TRUESpace: FALSEString: 'HELLO'As shown above, the order of characters in the output string corresponds to the order of input bytes, that is the byte value at the first position of Array[1..255]...
First use an encoding to convert the string to an array of bytes. I suggest UTF8 or ASCII. Then use Convert.ToString( n, 2 ) to convert each byte to a string in base 2. (using 1's and 0's.) You can use .PadLeft( 8, '0' ) to ensure that there are leading zeroes and tha...
