如何将一组更改放到一个数组中，然后在C++中将所有更改打印为一个

#include <iostream>
#include <sstream>
#include <vector>

std::string printChanges(const std::vector<std::string>& changes) {
    std::stringstream ss;
    for (const auto& change : changes) {
        ss << change << " ";
    }
    return ss.str();
}

int main() {
    std::vector<std::string> changes = {"change1", "change2", "change3"};
    std::string result = printChanges(changes);
    std::cout << result << std::endl;
    return 0;
}
