string stream in c++

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

int main() {
    // Step 1: Declare a stringstream object
    std::stringstream ss;

    // Step 2: Declare variables
    int integerVar = 42;
    double doubleVar = 3.14;
    std::string stringVar = "Hello, World!";

    // Step 3: Use the stringstream to convert variables to strings
    ss << "Integer: " << integerVar << ", Double: " << doubleVar << ", String: " << stringVar;

    // Step 4: Retrieve the concatenated string
    std::string result = ss.str();

    // Step 5: Display the result
    std::cout << result << std::endl;

    return 0;
