in Cu can declare a variable outside but u should extern key word before it"extern int i;" u can't intilize the the variable outsideas i=5; this is wrong if u want intilize it make it as static "static int i=5;" in C++ u cant declare variables outside outside ,if u want to declare use extern key word otherwise declare it in one class the class as default constructor in it it will automatically initilize the variable inside the class
