showpos

Causes positive numbers to be explicitly signed.

ios_base& showpos( 
   ios_base& _Str 
);

매개 변수

• _Str
  A reference to an object of type ios_base, or to a type that inherits from ios_base.

반환 값

A reference to the object from which _Str is derived.

설명

noshowpos is the default.

The manipulator effectively calls _Str.setf(ios_base::showpos), and then returns _Str.

예제

// compile with: /EHsc

int main( ) 
{
   using namespace std;
   int i = 1;

   cout << noshowpos << i << endl;   // noshowpos is default
   cout << showpos << i << endl;
}
