Q2. Why c is faster than java or python
Ans. 
C is faster than Java or Python due to its lower-level nature and direct hardware access.
• C is a low-level language that allows for direct memory manipulation and hardware access, resulting in faster performance.

• Java and Python are higher-level languages with more abstractions, leading to slower execution compared to C.

• C code is compiled directly to machine code, while Java and Python code are typically interpreted or r...read more
