vector to string c++

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

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

    std::ostringstream oss;
    for (const auto& num : numbers) {
        oss << num << " ";
    }

    std::string result = oss.str();

    std::cout << "Resulting string: " << result << std::endl;

    return 0;
}

1. Include Libraries: Import necessary libraries (iostream, vector, string, sstream) to work with vectors and strings.

2. Main Function: Define the main() function, the entry point of the program.

3. Vector Initialization: Create a vector named numbers and initialize it with integers 1 to 5.

4. String Stream Object: Declare an ostringstream object named oss. This object will be used to manipulate the content of the string.

5. Loop Through Vector: Iterate through each element in the numbers vector using a range-based for loop.

6. Append Numbers to String Stream: Inside the loop, each number from the vector is appended to the ostringstream object followed by a space.

7. Convert String Stream to String: Get the resulting string from the ostringstream object by calling oss.str() and store it in the result variable.

8. Display Result: Output the final string (result) containing the vector elements separated by spaces to the standard output using std::cout.

9. Return: End the main() function and return 0 to indicate successful completion of the program.
