ios manipulators skipws() function in C++

The skipws() method of stream manipulators in C++ is used to set the skipws format flag for the specified str stream. This flag skips the whitespaces in the input stream before the first non-whitespace character. Syntax:

ios_base& skipws (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 skipws format flag set. Example 1:

CPP

// C++ code to demonstrate
// the working of skipws() 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 skipws()
    iss >> skipws >> a >> b >> c;

    cout << "skipws flag: "
         << a << endl
         << b << endl
         << c << endl;

    return 0;
}

Output:

skipws flag: G
F
G

Example 2:

CPP

// C++ code to demonstrate
// the working of skipws() function

#include <iostream>
#include <sstream>

using namespace std;

int main()
{

    // Initializing the character
    char a;

    // Stream input with leading whitespaces
    istringstream iss("        G");

    // Using skipws()
    iss >> skipws >> a;

    cout << "skipws flag: "
         << a << endl;

    return 0;
}

Output:

skipws flag: G
