How to Split a String by New Line in C++ ?

Answer

In C++, you can split a string by new line using the std::getline function with the newline character '\n'.

✐ Examples

1 Split by New Line

In this example,

We create a string named str with a value containing new lines.
We use the std::istringstream class to create an input string stream from str.
We use the std::getline function with the newline character '\n' to split the string into substrings.
We iterate over the substrings and print them.

C++ Program

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

int main() {
    std::string str = "Hello\nWorld\n";
    std::istringstream iss(str);
    std::string token;
    while (std::getline(iss, token, '\n')) {
        std::cout << token << std::endl;
    }
    return 0;
}

Output

Hello
World
