In C, struct keyword must be used for declaring structure variables, but it is optional in C++.

For example, following program gives error in C and works in C++.




struct node {
   int x;
   node *next; // Error in C, struct must be there. Works in C++
};
  
int main()
{
   node a;  // Error in C, struct must be there. Works in C++
}


And following program works in both C and C++.




struct node {
   int x;
   struct node *next;  // Works in both C and C++
};
  
int main()
{
   struct node a;  // Works in both C and C++
}
