*a = *a ^ *b; *b = *a ^ *b; *a = *a ^ *b; | Limitation | Suggestion | |------------|-------------| | Some articles have inconsistent formatting | Cross-check with “The C Programming Language” (K&R) | | Not all code is strictly standard C (some Turbo C legacy) | Compile with -Wall -pedantic in GCC | | Limited project-based learning | Use GFG + build your own shell or text editor | Conclusion GeeksforGeeks is not just a reference — it’s an interactive coding companion for C. Whether you are preparing for a GATE exam, a placement interview, or want to deeply understand pointers and memory, GFG’s structured content and practice problems are invaluable.

Happy coding! – Write once, compile anywhere (almost). int main() int x = 5, y =

int main() int x = 5, y = 10; swap(&x, &y); printf("x = %d, y = %d", x, y); // x = 10, y = 5 return 0;
