How to split string in C++?

In this tutorial, we will show you ways of splitting a string by comma and space in C++.

There are different ways you can achieve this task.

Using stringstream and getline() function to split string

We can use getline() function and stringstream to split strings in C++.

First, have a look at the following C++ program and then I will explain how it works:

#include <iostream>

#include <sstream>

using namespace std;

int main()

{

    string str_Spl, str_piece;

    //String to split
    str_Spl = "C++ is cool program language, love it!";


    //Creating an object of stringstream
    stringstream obj_ss(str_Spl);

    cout <<"Source String to Split: " <<str_Spl << "\n\n";

    // getline() function to go through source string until it is finished.

    while (getline(obj_ss, str_piece, ' ')) {
        cout << str_piece << endl;
    }

    return 0;

}

Output:

CPP-split-string-space

You can see, the above string is split by a space delimiter.

So, how it worked?
  • We associated a string object (str_Spl) to stringstream. Stringstream allows reading from the string.
  • The getline() is used. It takes three parameters including the delimiter. There you may specify a space, comma, or any other desired character that you want to split a string.
  • You may learn more about getline() function in its tutorial.

Using comma as delimiter to split strings in C++

The program below splits the string by comma delimiter.

#include <iostream>
#include <sstream>
using namespace std;

int main()

{
    string str_Spl, str_piece;

    //String to split
    str_Spl = "Banana,Mango,Apple,Grapes";

    //Creating an object of stringstream
    stringstream obj_ss(str_Spl);

    cout <<"Source String to Split: " <<str_Spl << "\n\n";

    // while loop function to go through source string until it is finished.
    while (getline(obj_ss, str_piece, ',')) {
        cout << str_piece << endl;
    }
    return 0;

}

Output:

CPP-split-string-comma

Taking user input for source string to split

In this example, we take the input from the user to enter the string to split by space delimiter.

#include <iostream>
#include <sstream>

using namespace std;

int main()
{
    string str_Spl, str_piece;

    //Taking User Input
    cout << "Enter a line to split by space? ";

    getline(cin, str_Spl);

    stringstream obj_ss(str_Spl);

    // while loop function to go through source string until it is finished.
    cout << "\nString after Split: \n\n ";

    while (getline(obj_ss, str_piece, ' ')) {
        cout << str_piece << endl;
    }

    return 0;

}

 

Sample Output:

CPP-split-user-input
