在 C++ 中将 int[] 转换为 String

#include<iostream>
#include <sstream>
#include<string>

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int size = sizeof(arr) / sizeof(arr[0]);

    std::ostringstream oss;
    for (int i = 0; i< size; ++i) {
        oss<< arr[i];
        if (i< size - 1) {
            oss << ", ";
        }
    }

    std::string result = oss.str();
    std::cout << "String: "<< result<< std::endl;

    return 0;
}

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

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int size = sizeof(arr) / sizeof(arr[0]);

    std::vector<std::string> str_arr;
    for (int i = 0; i< size; ++i) {
        str_arr.push_back(std::to_string(arr[i]));
    }

    std::string result = "";
    for (int i = 0; i< size; ++i) {
        result += str_arr[i];
        if (i< size - 1) {
            result += ", ";
        }
    }

    std::cout << "String: "<< result<< std::endl;

    return 0;
}
