C++ -将字符向量元素转换为单个uint64

#include <vector>
#include <cstdint>

std::vector<char> charVector = {'a', 'b', 'c', 'd'};

uint64_t convertToUint64(const std::vector<char>& charVector) {
    uint64_t result = 0;
    for (const auto& c : charVector) {
        result = (result << 8) | static_cast<uint64_t>(c);
    }
    return result;
}

uint64_t convertedValue = convertToUint64(charVector);
std::cout << "Converted value: " << convertedValue << std::endl;
