将字符串复制到缓冲区中

#include<string.h>

char buffer[100];
char str[] = "Hello, world!";

strcpy(buffer, str);

buffer = bytearray(100)
str = "Hello, world!"

buffer[:len(str)] = str.encode()

char[] buffer = new char[100];
String str = "Hello, world!";

System.arraycopy(str.toCharArray(), 0, buffer, 0, str.length());
