c ++ splitlines

To split a string into lines in C++, you can use the std::istringstream class and the std::getline function. Here are the steps to accomplish this:

1. Include the necessary headers:

#include <sstream>
#include <vector>

1. Declare a string variable to store your input string:

std::string inputString;

1. Read the input string from the user:

std::getline(std::cin, inputString);

1. Declare a std::istringstream object and initialize it with the input string:

std::istringstream iss(inputString);

1. Declare a vector to store the individual lines:

std::vector<std::string> lines;

1. Use a while loop to read each line from the std::istringstream and store it in the vector:

std::string line;
while (std::getline(iss, line)) {
    lines.push_back(line);
}

1. Now, the lines vector contains each line of the input string as separate elements.

Here's the complete code snippet:

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

int main() {
    std::string inputString;
    std::getline(std::cin, inputString);

    std::istringstream iss(inputString);

    std::vector<std::string> lines;
    std::string line;
    while (std::getline(iss, line)) {
        lines.push_back(line);
    }

    // Use the 'lines' vector as needed
    for (const auto& line : lines) {
        std::cout << line << std::endl;
    }

    return 0;
}

This code will split the input string into separate lines and store them in a vector. You can then use the lines vector to process or display each line separately.
