iomanip resetiosflags() function in C++ with Examples
  • Last Updated : 11 Oct, 2019

The resetiosflags() method of iomaip library in C++ is used to reset the ios library format flags specified as the parameter to this method.

Syntax:

resetiosflags (ios_base::format_flag)

Parameters: This method accepts format_flag as a parameter which is the ios library format flag to be reset by this method.

Return Value: This method does not returns anything. It only acts as stream manipulators.

Example 1:






// C++ code to demonstrate
// the working of resetiosflags() function
  
#include <iomanip>
#include <ios>
#include <iostream>
  
using namespace std;
  
int main()
{
  
    // Initializing the integer
    int num = 50;
  
    cout << "Before reset: \n"
         << hex
         << setiosflags(ios::showbase)
         << num << endl;
  
    // Using resetiosflags()
    cout << "Resetting showbase flag"
         << " using resetiosflags: \n"
         << resetiosflags(ios::showbase)
         << num << endl;
  
    return 0;
}
Output:
Before reset: 
0x32
Resetting showbase flag using resetiosflags: 
32

Example 2:




// C++ code to demonstrate
// the working of resetiosflags() function
  
#include <iomanip>
#include <ios>
#include <iostream>
  
using namespace std;
  
int main()
{
  
    // Initializing the integer
    int num = 50;
  
    cout << "Before reset: \n"
         << hex
         << setiosflags(ios::showbase)
         << num << endl;
  
    // Using resetiosflags()
    cout << "Resetting showbase and uppercase"
         << " flag using resetiosflags: \n"
         << resetiosflags(ios::showbase)
         << num << endl;
  
    return 0;
}
Output:
Before reset: 
0x32
Resetting showbase and uppercase flag using resetiosflags: 
32
