ios manipulators nounitbuf() function in C++
The nounitbuf() method of stream manipulators in C++ is used to clear the showbase format flag for the specified str stream. This flag does not flushes the associated buffer after each operation.
Syntax:
ios_base& nounitbuf (ios_base& str)
Parameters: This method accepts str as a parameter which is the stream for which the format flag is to be cleared.
Return Value: This method returns the stream str with nounitbuf format flag set.
Example 1:
// C++ code to demonstrate // the working of nounitbuf() function #include <iostream> #include <sstream> using namespace std; int main() { // Initializing the character char a, b, c; // Stream input with leading whitespaces istringstream iss( "GFG" ); // Using nounitbuf() iss >> nounitbuf >> a >> b >> c; cout << "nounitbuf flag: " << a << endl << b << endl << c << endl; return 0; } |
Output:
nounitbuf flag: G F G
Example 2:
// C++ code to demonstrate // the working of nounitbuf() function #include <iostream> #include <sstream> using namespace std; int main() { // Initializing the character char a, b, c, d, e; // Stream input with leading whitespaces istringstream iss( "Beginner" ); // Using nounitbuf() iss >> nounitbuf >> a >> b >> c >> d >> e; cout << "nounitbuf flag: " << a << endl << b << endl << c << endl << d << endl << e << endl; return 0; } |
Output:
nounitbuf flag: G E E K S
