c++ 2进制转16进制字符串

在C中将二进制转换为十六进制字符串有一个函数可以实现，可以使用下面的方法:

std::string BinToHex(const std::string &strBin, bool bIsUpper = false) {
    std::string strHex;
    strHex.resize(strBin.size() * 2);
    for (size_t i = 0; i < strBin.size(); i++) {
        uint8_t cTemp = strBin[i];
        for (size_t j = 0; j < 2; j++) {
            uint8_t cCur = (cTemp & 0x0f);
            if (cCur < 10) {
                cCur += '0';
            } else {
                cCur += ((bIsUpper ? 'A' : 'a') - 10);
            }
            strHex = cCur;
            cTemp >>= 4;
        }
    }
    return strHex;
}

这个函数会将输入的二进制字符串转换为十六进制字符串。你可以调用这个函数来实现你的需求。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
