How to convert a vector of ints to a vector of strings in C++

Answer 1

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

std::vector<std::string> convertToStringArray(const std::vector<int>& numbers) {
    std::vector<std::string> stringArray;

    for (int num : numbers) {
        stringArray.push_back(std::to_string(num));
    }

    return stringArray;
}

int main() {
    std::vector<int> numbers = {1, 2, 3, 4, 5};

    // Convert the list of integers to a string vector
    std::vector<std::string> stringArray = convertToStringArray(numbers);

    std::cout << "String vector:" << std::endl;
    for (const std::string& str : stringArray) {
        std::cout << str << std::endl;
    }

    return 0;
}
