Context & Indian CS Lab Dilemma:

Question: Print an empty square of side 10 using *. Modern students utilize if (r==0 || r==9 || c==0 || c==9) inside nested loops. In many college exams, external evaluators deduct marks because the official lab manual mandated 3 separate loops (top border, side columns, bottom border), or insisted on Turbo C++ void main() with conio.h.

📜 Vintage Lab Manual Grader Marks: 4 / 10
Flagged / Deducted: Deviated from 3-separate loop manual pattern; missing conio.h clrscr()
  • Missing #include <conio.h> and clrscr()
  • Did not use standard 3-loop manual pattern
  • Using C99 standard int main() without getch() freeze
⚙️ Modern ISO Semantic Compiler Score: 10 / 10
Passed: Clean O(N^2) boundary logic, C99/C11 compliant, 0 memory overhead
  • Time Complexity: O(N²) optimal single-pass matrix traversal
  • Auxiliary Space: O(1) in-place rendering
  • Standard: ISO C99/C11 compliant main() exit code 0
