noshowpos


manipulator function
<ios>
ios_base& noshowpos ( ios_base& str );

Do not show positive signs

Clears the showpos format flag for the str stream.

When the showpos format flag is not set, no plus signs precedes any positive (nor zero) value.

This flag can be set with the showpos manipulator, which forces the writting of a plus sign (+) before every non-negative numerical value insterted into the stream, including zero values.

The showpos flag is not set in standard streams on initialization.

Parameters

str
Stream object where to apply.
Because this function is a manipulator, it is designed to be used alone with no arguments in conjunction with the insertion (<<) and extraction (>>) operations on streams (see example below).


Return Value

A reference to the stream object.

// modify showpoint flag
#include <iostream>
using namespace std;

int main () {
  signed int p, z, n;
  p=1;
  z=0;
  n=-1;
  cout << noshowpos << p << '\t' << z << '\t' << n << endl;
  cout <<   showpos << p << '\t' << z << '\t' << n << endl;
  return 0;
}


The execution of this example displays something similar to:
1       0       -1
+1      +0      -1
