The showbase() method of stream manipulators in C++ is used to set the showbase format flag for the specified str stream. This flag displays the integers along with their base prefixes.
Syntax:
ios_base& showbase (ios_base& str)
Parameters: This method accepts str as a parameter which is the stream for which the format flag is affected.
Return Value: This method returns the stream str with showbase format flag set.
Example 1:
// C++ code to demonstrate
// the working of showbase() function
#include <iostream>
using namespace std;
int main()
{
// Initializing the integer
int num = 50;
// Using showbase()
cout << "showbase flag: "
<< hex
<< showbase
<< num << endl;
return 0;
}
Output:
showbase flag: 0x32
Example 2:
// C++ code to demonstrate
// the working of showbase() function
#include <iostream>
using namespace std;
int main()
{
// Initializing the integer
int num = 50;
// Using showbase()
cout << "showbase flag: "
<< oct
<< showbase
<< num << endl;
return 0;
}
Output:
showbase flag: 062
