extern int var; int main(void) { var = 10; // why it is not considered as definition in prog return 0; } Why this is creating error saying (var is not defined).But as per rule -"by externing a variable we can use the variables anywhere in the program provided we know the declaration of them and the variable is defined somewhere."?
