ios manipulators noskipws() function in C++

The noskipws() method of stream manipulators in C++ is used to clear the showbase format flag for the specified str stream. This flag reads the whitespaces in the input stream before the first non-whitespace character.

Syntax:

ios_base& noskipws (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 noskipws format flag set.

Example 1:

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

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

    return 0;
}

Output:

noskipws flag:

Example 2:

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

#include <iostream>
#include <sstream>

using namespace std;

int main()
{

    // Initializing the character
    char c;

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

    // Using noskipws()
    iss >> noskipws >> c;

    cout << "noskipws flag: "
         << c << endl;

    return 0;
}

Output:

noskipws flag:
