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:
