Single-Line Conditional: (condition) ? printf("True") : printf("False"); 4. Using Bitwise Operators: // Toggle a bit x ^= (1 << n); 5. String Length Without strlen: int length(const char *str) { const char *s; for (s = str; *s; ++s); return s - str; } 6. Variable-Length Arrays: int n; scanf("%d", &n); int arr[n]; // Size defined at runtime 7. Inline Assembly: asm("movl %eax, %ebx"); // Inline assembly code These tricks can help improve code efficiency, readability, and debugging. read less
