ios manipulators noboolapha() function in C++

Last Updated : 28 Aug, 2019

The noboolalpha() method of stream manipulators in C++ is used to get the integral value of boolapha format flag for the specified str stream. Syntax:

ios_base& noboolalpha (ios_base& str)

Parameters: This method accepts str as a parameter which is the stream for which the format flag is fetched. Return Value: This method returns the stream str with noboolalpha format flag . Example 1:

CPP

// C++ code to demonstrate
// the working of noboolalpha() function

#include <iostream>

using namespace std;

int main()
{

    // Initializing the boolean flag
    bool flag = true;

    // Using noboolalpha()
    cout << "noboolalpha flag: "
         << noboolalpha << flag << endl;

    return 0;
}

Output:

noboolalpha flag: 1

Example 2:

CPP

// C++ code to demonstrate
// the working of noboolalpha() function

#include <iostream>

using namespace std;

int main()
{

    // Initializing the boolean flag
    bool flag = false;

    // Using noboolalpha()
    cout << "noboolalpha flag: "
         << noboolalpha << flag << endl;

    return 0;
}

Output:

noboolalpha flag: 0
