The setiosflags() method of iomanip library in C++ is used to set the ios library format flags specified as the parameter to this method.
Syntax:
setiosflags (ios_base::format_flag)
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:
CPP
// 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:
CPP
// 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)
<< num << endl;
return 0;
} |
Output:
Setting showbase and uppercase flag using setiosflags: 0X32
