function
std::noshowpos
<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.
Example

cout << showpos << p << '\t' << z << '\t' << n << endl;
return 0;
