function
std::nouppercase
<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.
Example

// modify uppercase flag
#include <iostream>
using namespace std;
int main () {
cout << showbase << hex;
cout << nouppercase << 77 << endl;
cout << uppercase << 77 << endl;
return 0;
}
