2. 编写函数将16进制string转换为byte数组 以下是一个C函数,用于将16进制字符串转换为unsigned char数组: c #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ctype.h> unsigned char* hexStringToByteArray(const char* hexString, size_t* outputLengt...

There's another aspect of the interface that's hard to use: the return value is naturally zero if given an empty string, however, we also overload that to indicate an error (in which case some of the output buffer may have been written). That's not an ideal interface design - perha...
| hexCharToInt(s.at(i+1))); } return ret; } string bytestohexstring(char* bytes,int bytelength) { string str(""); string str2("0123456789abcdef"); for (int i=0;i<bytelength;i++) { int b; b = 0x0f&(bytes[i]>>4); ...
方法一:使用int()和to_bytes()函数 在Python中,可以使用int()函数将16进制字符串转换为整数,然后使用to_bytes()函数将整数转换为字节。以下是示例代码: hex_string="FFA0"integer=int(hex_string,16)byte=integer.to_bytes((len(hex_string)+1)//2,byteorder='big')print(byte) ...
