ios manipulators showpos() function in C++
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:
// 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:
// 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
