需要从字节值转换为 DWORD(基于 ascii)!
例子:
输入:(1F 12 BA 43
保存在std::vector<BYTE>
)
输出:(31 46 31 32 42 41 34 33
输入的ascii值)->也存储在一个std::vector<BYTE>
进行这种转换的最简单方法是什么?
谢谢
typedef unsigned char BYTE;
typedef std::vector<BYTE> Vector;
Vector hex2ascii(Vector const &src) {
Vector result;
for ( Vector::const_iterator iter = src.begin(); iter!=src.end(); iter++ ) {
BYTE item = *iter;
unsigned bits=8;
do {
bits -= 4;
result.push_back("0123456789ABCDEF"[(item>>bits)&15u]);
} while(bits);
}
return result;
}
