In modern C++, uniform initialization is a convenient way to initialize objects, including standard library types. One such type is std::stringstream which provides a flexible way to work with strings as streams. In this blog post, we will explore how to initialize and use std::stringstream using uniform initialization.

Initialization of std::stringstream Using Uniform Initialization

Prior to C++11, std::stringstream had to be initialized using the constructor. However, with the introduction of uniform initialization, we can now initialize std::stringstream objects more easily and concisely.

#include <sstream>

int main() {
    // Initializing std::stringstream using uniform initialization
    std::stringstream ss{"Hello, World!"};

    // Rest of the code here...

    return 0;
}

In the above code snippet, we create a std::stringstream object named ss and initialize it with the string "Hello, World!" using uniform initialization.

Using std::stringstream object

Once we have initialized the std::stringstream object, we can use it to perform various operations on strings, such as extracting data or manipulating the contents. Here is a simple example:

#include <iostream>
#include <sstream>

int main() {
    std::stringstream ss{"C++ is great!"};

    std::string word;
    while (ss >> word) {
        std::cout << word << std::endl;
    }

    return 0;
}

The code snippet above demonstrates how to extract individual words from the std::stringstream object ss and then print them. The ss >> word statement extracts words from the stream one-by-one until all the words have been retrieved.

Conclusion

Uniform initialization in C++ provides a cleaner and more concise way to initialize standard library types, such as std::stringstream. By leveraging uniform initialization, we can easily initialize std::stringstream objects with strings and perform various operations on them.

Using uniform initialization not only improves code readability but also aligns with the modern C++ coding style. It is recommended to use uniform initialization whenever possible in order to write more expressive and maintainable code.
