@sanju, if u declare a variable with extern, at compile time its defn is nt
looked for, rather @ link time corresponding defn is looked for by the
linker. nd if the defn is nt ther, it will raise a linker error, as in case
of this prog
@rahul, ya off course, for a variable to be global it hs to be defined at
file scope.
