+3. **03_data_types.c**  
+   Demonstrates different data types in C (int, float, double, char) and their storage sizes.  
+
+4. **04_constants.c**  
+   Introduction to constants (`const` keyword) and why immutability matters.  
+
+5. **05_operators.c**  
+   Examples of arithmetic, assignment, comparison, and logical operators.  
+
