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

Answer 1

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

std::string convertVectorToString(const std::vector<std::string>& stringVector, const std::string& delimiter = "") {
    std::string result;

    for (size_t i = 0; i < stringVector.size(); ++i) {
        result += stringVector[i];
        // Add delimiter except for the last element
        if (i < stringVector.size() - 1) {
            result += delimiter;
        }
    }

    return result;
}

int main() {
    std::vector<std::string> words = {"C++", "C", "Java", "Python"};

    std::string concatenatedString = convertVectorToString(words, " ");

    std::cout << concatenatedString << std::endl;

}
