Parameters: This method accepts format_flag as a parameter which is the ios library format flag to be set 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 setiosflags() function
  
#include <iomanip>
#include <ios>
#include <iostream>
  
using namespace std;
  
int main()
{
  
    // Initializing the integer
    int num = 50;
  
    // Using setiosflags()
    cout << "Setting showbase flag "
         << "using setiosflags: \n"
         << hex
         << setiosflags(ios::showbase)
         << num << endl;
  
    return 0;
}


Output:

Setting showbase flag using setiosflags: 
0x32

Example 2:




// C++ code to demonstrate
// the working of setiosflags() function
  
#include <iomanip>
#include <ios>
#include <iostream>
  
using namespace std;
  
int main()
{
  
    // Initializing the integer
    int num = 50;
  
    // Using setiosflags()
    cout << "Setting showbase and uppercase"
         << " flag using setiosflags: \n"
         << hex
         << setiosflags(
                ios::showbase
                | ios::uppercase)
