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:

// 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:

// 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; 
}
