How to Take Multiple String Inputs in a Single Line in C++?

In C++, strings are used to store textual data. While working with user input, we often may need to take multiple string inputs in a single line only. In this article, we will learn how to take multiple string inputs in a single line.

Example

Input:
Hi,Geek,Welcome,to,GfG
delimiter = ','

Output:
String 1: Hi
String 2: Geek
String 3: Welcome
String 4: to
String 5: GfG

Take Multiple String Inputs in C++

To take multiple string inputs in a single line, we can use the std::getline() function with a user-defined delimiter (like space, semicolon, comma, etc) that indicates the end of one string. We can then tokenize that string using the stringstream and geline() function.

C++ Program to Take Multiple String Inputs

// C++ program to take multiple string inputs in a single
// line.
#include <iostream>
#include <sstream>
#include <string>
using namespace std;

int main()
{
    string input;
    string delimiter;

    cout << "Enter multiple strings separated by a custom "
            "delimiter: ";
    getline(cin, input);

    // Prompt the user to enter a custom delimiter
    cout << "Enter the delimiter: ";
    getline(cin, delimiter);

    // Using stringstream to tokenize the input based on the
    // custom delimiter
    stringstream ss(input);
    string token;
    int i = 1;
    while (getline(ss, token, delimiter[0])) {
        // Process each string token
        cout << "String " << i << " " << token << endl;
        i++;
    }

    return 0;
}

Output

Enter multiple strings separated by a custom delimiter: Hi,Geek,Welcome,to,GfG
Enter the delimiter: ,
String 1 Hi
String 2 Geek
String 3 Welcome
String 3 to
String 4 GfG
