Summary

Locale convenience function that converts a character to upper case

Synopsis

#include <locale>
namespace std {
 template <class charT> 
 charT toupper(charT c, const locale& loc);
}

Description

The toupper() function returns the parameter c after converting it to upper case. The conversion is made using the ctype facet from the locale parameter.

Example

//
// toupper.cpp
//
 
#include <iomanip> // for setw
#include <iostream> // for cout, endl
int main ()
{
 std::cout << std::oct;
 std::cout.fill ('0');
 // compute tolower and toupper of printable ASCII characters
 for (int c = ' '; c != '~' + 1; ++c)
 std::cout << "std::toupper/lower ('\\" << std::setw (3) 
 << c
 << "', std::locale ()) = '"
 << std::toupper (char (c), std::cout.getloc ())
 << "' / "
 << std::tolower (char (c), std::cout.getloc ())
 << "'\n";
 
 return 0;
}
