Generically, function objects are instances of a class with member function operator() defined. This member function allows the object to be used with the same syntax as a regular function call, and therefore it can be used in templates instead of a pointer to a function. text/html 2010-03-17T11:31:29-07:00 Nate Kohl http://www.cppreference.com/wiki/keywords/static?rev=1268850689&do=diff static The static keyword can be used in four different ways: * to create permanent storage for local variables in a function, * to create a single copy of class data, * to declare member functions that act like non-member functions, and * to specify internal linkage. text/html 2010-03-16T20:03:11-07:00 http://www.cppreference.com/wiki/es/c/string/isalpha?rev=1268794991&do=diff isalpha Syntax: #include <cctype> int isalpha( int ch ); La funcion isalpha() retorna un numero distinto de cero si el argumento es una letra del alfabeto.
