showpos
Causes positive numbers to be explicitly signed.
ios_base& showpos(
ios_base& _Str
);
Parameters
- _Str
A reference to an object of type ios_base, or to a type that inherits from ios_base.
Return Value
A reference to the object from which _Str is derived.
Remarks
noshowpos is the default.
The manipulator effectively calls _Str.setf(ios_base::showpos), and then returns _Str.
Example
// ios_showpos.cpp
// compile with: /EHsc
#include <iostream>
int main( )
{
using namespace std;
int i = 1;
cout << noshowpos << i << endl; // noshowpos is default
cout << showpos << i << endl;
}
