nouppercase


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

Do not generate upper case letters

Clears the uppercase format flag for the str stream.

When the uppercase format flag is not set, the letters automatically generated by the stream for certain representations, like some hexadecimal representations and numerical base prefixes, are not forced to be displayed using uppercase letters, hence being displayed using mostly lowercase letters.

This flag can be set with the uppercase manipulator, forcing the use of uppercase for generated letters.

The uppercase 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 uppercase flag
#include <iostream>
using namespace std;

int main () {
  cout << showbase << hex;
  cout << nouppercase << 77 << endl;
  cout << uppercase << 77 << endl;
  return 0;
}


The execution of this example displays something similar to:
0x4d
0X4D
