why c in embedded ?

C is the most popular programming language for embedded systems for a number of reasons, including:

• Efficiency: C code is typically very efficient, both in terms of memory usage and execution speed. This is important for embedded systems, which often have limited resources.
• Portability: C compilers are available for a wide range of microcontrollers and other embedded systems hardware. This makes it easy to port C code from one platform to another.
• Control: C programmers have direct control over hardware resources, such as memory and peripherals. This is important for embedded systems, where performance and reliability are often critical.
• Maturity: C is a mature language with a large community of users and developers. This means that there are many resources available to help C programmers, including libraries, tools, and documentation.

Here are some specific examples of how C's features are beneficial for embedded systems programming:

• Memory management: C gives programmers direct control over memory allocation and deallocation. This is important for embedded systems, where memory is often a limited resource.
• Data types: C provides a variety of data types, including primitive types (such as int, char, and float) and user-defined types (such as structs and enums). This allows programmers to efficiently represent the data that their embedded systems need.
• Pointers: C pointers allow programmers to directly access memory locations. This is important for embedded systems, where programmers often need to interact directly with hardware.
• Bit manipulation: C provides operators for bit-level operations, such as AND, OR, and XOR. This is useful for embedded systems, where programmers often need to control hardware at a low level.

In addition to the above, C is also a relatively simple language to learn, which makes it a good choice for embedded systems programmers.

Overall, C is the best choice for embedded systems programming because it is efficient, portable, gives programmers control over hardware resources, and is mature and well-supported.
