Programming fundamentals in C and Python

C is a compiled, statically typed, procedural language designed for close control over hardware resources. A C source file is normally preprocessed, compiled, assembled and linked before execution. The preprocessor expands directives such as `#include` and `#define`; the compiler translates C into machine-level object code; the linker combines object files and libraries into an executable. Because most type information is fixed at compile time, many type errors are caught before the programme runs. C gives the programmer control over storage duration, addresses and layout, but it also expects careful handling of memory, array bounds and pointer validity.

Python is usually described as an interpreted, dynamically typed, high-level language. In the common CPython implementation, source code is compiled into bytecode and then run by a virtual machine. Types belong to objects at runtime, so the same variable name may later refer to an integer, a list or a string. This model favours short programmes, interactive testing and rapid automation. The cost is slower raw execution for tight loops and less compile-time checking. For RSSB computer-instructor level MCQs, the important contrast is not "fast versus slow" alone; it is compile-time type discipline and explicit memory control in C versus runtime flexibility and built-in abstractions in Python.

Core distinction: C prioritises predictable low-level control after compilation, while Python prioritises readable, flexible execution through a runtime environment.
