How to Split a String in C++ ?

Answer

In C++, you can split a string using the std::istringstream or the boost::split function from the Boost library.

✐ Examples

1 Split by Space

In this example,

We create a string named str with a value of "Hello World".
We use the std::istringstream to split the string into tokens.
We iterate over the tokens and print them.

C++ Program

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

int main() {
    std::string str = "Hello World";
    std::istringstream iss(str);
    std::vector<std::string> tokens;
    std::string token;

    while (iss >> token) {
        tokens.push_back(token);
    }

    for (const auto& t : tokens) {
        std::cout << t << std::endl;
    }

    return 0;
}

Output

Hello
World

2 Split by Comma

In this example,

We create a string named str with a value of "apple,banana,cherry".
We use the boost::split function to split the string into tokens.
We iterate over the tokens and print them.

C++ Program

#include <iostream>
#include <vector>
#include <string>
#include <boost/algorithm/string.hpp>

int main() {
    std::string str = "apple,banana,cherry";
    std::vector<std::string> tokens;
    boost::split(tokens, str, boost::is_any_of(","));

    for (const auto& t : tokens) {
        std::cout << t << std::endl;
    }

    return 0;
}

Output

apple
banana
cherry
