🌸 NAME 🌸

okay bestie, this is the C++ Standard Libary page for std::basic_ostringstream::view — and the NAME line is literally std::basic_ostringstream::view - std::basic_ostringstream::view. 💖

✨ Synopsis ✨

std::basic_string_view<CharT, Traits> view() const noexcept;  (since
C++20)

Obtains a std::basic_string_view over the underlying string object. Equivalent to:

return rdbuf()->view();

💖 Parameters 💖

(none) — no parameters, she takes zero notes. 🫶

🌟 Return value 🌟

A std::basic_string_view over the underlying string object. periodt. ✨

🔥 Example 🔥

// Run this code

#include <iostream>
#include <sstream>

int main()
{
    // input/output stream
    std::stringstream buf1;
    buf1 << 69;
    int n = 0;
    buf1 >> n;
    std::cout << "1) buf1 = [" << buf1.view() << "], n = " << n <<
'\n';

    // output stream in append mode
    std::ostringstream buf2("test", std::ios_base::ate);
    buf2 << '1';
    std::cout << "2) buf2 = [" << buf2.view() << "]\n";

    // input stream
    std::istringstream inbuf("-42");
    inbuf >> n;
    std::cout << "3) inbuf = [" << inbuf.view() << "], n = " << n <<
'\n';
}

🍓 Output: 🍓

1) buf1 = [69], n = 69
2) buf2 = [test1]
3) inbuf = [-42], n = -42
