The setbase() method of iomanip library in C++ is used to set the ios library basefield flag based on the argument specified as the parameter to this method.
Syntax:
setbase (int base)
Parameters: This method accepts base as a parameter which is the integer argument corresponding to which the base is to be set. 10 stands for dec, 16 stands for hex, 8 stands for oct, and any other value stands for 0 (reset).
Return Value: This method does not returns anything. It only acts as stream manipulators.
Example 1:
CPP
// C++ code to demonstrate // the working of setbase() function #include <iomanip> #include <ios> #include <iostream> using namespace std;
int main()
{ // Initializing the integer
int num = 50;
cout << "Before set: \n"
<< num << endl;
// Using setbase()
cout << "Setting base to hex"
<< " using setbase: \n"
<< setbase(16)
<< num << endl;
return 0;
} |
Output:
Before set: 50 Setting base to hex using setbase: 32
Example 2:
CPP
// C++ code to demonstrate // the working of setbase() function #include <iomanip> #include <ios> #include <iostream> using namespace std;
int main()
{ // Initializing the integer
int num = 50;
cout << "Before set: \n"
<< num << endl;
// Using setbase()
cout << "Setting base to oct"
<< " using setbase: \n"
<< setbase(8)
<< num << endl;
return 0;
} |
Output:
Before set: 50 Setting base to oct using setbase: 62
