将非null终止的vector<char>转换为字符串

#include <iostream>
#include <vector>
#include <string>

std::string convertVectorToString(const std::vector<char>& vec) {
    std::string result;
    for (const auto& ch : vec) {
        result += ch;
    }
    return result;
}

int main() {
    std::vector<char> vec = {'H', 'e', 'l', 'l', 'o'};
    std::string str = convertVectorToString(vec);
    std::cout << str << std::endl;
    return 0;
}
