ios_base& uppercase( 
   ios_base& _Str 


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

A reference to the object from which _Str is derived.

By default, nouppercase is in effect.

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

// ios_uppercase.cpp
// compile with: /EHsc
#include <iostream>

int main( void ) 
   using namespace std;
   double i = 1.23e100;
   cout << i << endl;
   cout << uppercase << i << endl;

   int j = 10;
   cout << hex << nouppercase << j << endl;
   cout << hex << uppercase << j << endl;
