ios manipulators noshowpos() function in C++

The noshowpos() method of stream manipulators in C++ is used to clear the showbase format flag for the specified str stream. This flag displays the non negative integer values without their + sign.

Syntax:

ios_base& noshowpos (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 noshowpos format flag set.

Example 1:

// C++ code to demonstrate 
// the working of noshowpos() function 
  
#include <iostream> 
  
using namespace std; 
  
int main() 
{ 
  
    // Initializing the integers 
    int a = 10; 
    int b = 0; 
  
    // Using noshowpos() 
    cout << "noshowpos flag: "
         << noshowpos 
         << a << endl 
         << b << endl; 
  
    return 0; 
} 

Output:

noshowpos flag: 10
0

Example 2:

// C++ code to demonstrate 
// the working of noshowpos() function 
  
#include <iostream> 
  
using namespace std; 
  
int main() 
{ 
  
    // Initializing the integers 
    int a = -10; 
  
    // Using noshowpos() 
    cout << "noshowpos flag: "
         << noshowpos 
         << a << endl; 
  
    return 0; 
} 

Output:

noshowpos flag: -10
