ios manipulators showpos() function in C++

Last Updated : 28 Aug, 2019

The showpos() method of stream manipulators in C++ is used to set the showpos format flag for the specified str stream. This flag always displays the non negative values along with their + sign. Syntax:

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

CPP

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

#include <iostream>

using namespace std;

int main()
{

    // Initializing the integers
    int a = 10;
    int b = 0;

    // Using showpos()
    cout << "showpos flag: "
         << showpos
         << a << endl
         << b << endl;

    return 0;
}

Output:

showpos flag: +10
+0

Example 2:

CPP

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

#include <iostream>

using namespace std;

int main()
{

    // Initializing the integers
    int a = -10;

    // Using showpos()
    cout << "showpos flag: "
         << showpos
         << a << endl;

    return 0;
}

Output:

showpos flag: -10
