std::basic_ios::fill(3)

✨ NAME ✨

std::basic_ios::fill — std::basic_ios::fill. okay so bestie, we're on the std::basic_ios::fill(3) page from the C++ Standard Libary, and the NAME section is literally serving the function name twice. iconic.

📜 Synopsis 📜

CharT fill() const;     (1)
CharT fill( CharT ch ); (2)

Okay so this function manages the fill character used to pad the output conversions to the specified field width. Two overloads, two little moments:

1. Returns the current fill character.
2. Sets the fill character to ch, returns previous value of the fill character.

🎀 Parameters 🎀

• ch — the character to use as fill character.

💖 Return value 💖

The fill character before the call to the function. periodt.

🌸 Example 🌸

        // Run this code

        #include <iomanip>
        #include <iostream>

        int main ()
        {
            std::cout << "With default setting : [" << std::setw(10) << 40 <<
       "]\n";
            char prev = std::cout.fill('x');
            std::cout << "Replaced '" << prev << "' with '"
                      << std::cout.fill() << "': [" << std::setw(10) << 40 <<
       "]\n";
        }

🦋 Output 🦋

With default setting : [        40]
