Scope of Variable 1 : Check Your C Skill

#include<stdio.h>
int num = 50 ;
//---------------
  void main()
  {
     int num = 20;
         printf("%d",num);
  }

1. Program contain 2 variables having same name.
2. num = 50 is Global , num = 20 is local Variable 
3. Note : In C Higher Priority is Given to Local Variables
