将vector<int>中的每个整数添加到字符串中

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

std::string addIntegersToString(const std::vector<int>& integers) {
    std::string result;
    
    for (const int& num : integers) {
        std::string numStr = std::to_string(num);
        result += numStr + " ";
    }
    
    return result;
}

int main() {
    std::vector<int> integers = {1, 2, 3, 4, 5};
    std::string result = addIntegersToString(integers);
    
    std::cout << "Result: " << result << std::endl;
    
    return 0;
}
