FAQs on Features of C++ Programming Language Video Lecture - Crash Course for EmSAT Achieve
| 1. What are the main features of the C programming language? |  |
Ans. The main features of the C programming language include:
- Portability: C programs can be written to run on different platforms without any changes.
- Efficiency: C allows low-level access to memory and provides efficient control over hardware.
- Modularity: C supports modular programming by dividing code into separate functions.
- Flexibility: C allows both high-level and low-level programming, making it suitable for various applications.
- Extensibility: C allows the use of external libraries and supports the creation of user-defined functions and data types.
| 2. Can you explain what is meant by portability in the context of the C programming language? | |
Ans. Portability in the context of the C programming language refers to the ability of C programs to be compiled and run on different platforms without any changes to the source code. This means that a C program written on one system can be easily transferred and executed on another system, provided that the necessary compiler and libraries are available. Portability is achieved by adhering to the standardized syntax and features of the C language, which ensures that the code behaves consistently across different environments.
| 3. How does the C programming language provide efficiency in terms of hardware control? | |
Ans. The C programming language provides efficiency in terms of hardware control through its low-level access to memory and the ability to manipulate hardware directly. C allows programmers to use pointers, which are variables that store memory addresses, to directly access and modify memory locations. This allows for efficient memory management and control. Additionally, C provides features such as bit manipulation, bitwise operators, and direct hardware input/output (I/O) operations, which enable programmers to optimize code for performance and interact with hardware at a low level.
| 4. What is modular programming, and how does C support it? | |
Ans. Modular programming is an approach to software design that involves dividing a program into separate, self-contained modules or functions. Each module performs a specific task and can be developed, tested, and maintained independently. C supports modular programming by allowing the code to be organized into separate functions, each responsible for a specific task. These functions can be written in isolation and then called from other parts of the program, making the code easier to understand, debug, and modify. C also supports the use of header files to provide interfaces for modules, facilitating code reuse and modularity.
| 5. Can you explain the concept of extensibility in the C programming language? | |
Ans. In the context of the C programming language, extensibility refers to the ability to extend the language's functionality by using external libraries and creating user-defined functions and data types. C allows programmers to include external libraries, which are collections of pre-compiled code, to add additional features and capabilities to their programs. These libraries can provide functions for tasks such as mathematical computations, file handling, and network communication. Furthermore, C allows programmers to define their own functions and data types, providing the flexibility to create custom functionality and structures that suit the specific needs of their applications.
