what is the difference between c and embedded c?
308972
Embedded C is generally an extension of the C language, they are more or less similar. However, some differences do exist, such as: C is generally used for desktop computers, while embedded C is for microcontroller based applications. C can use the resources of a desktop PC like memory, OS, etc.

The main difference between C and Python is that, C is a structure oriented programming language while Python is an object oriented programming language. ... Python has fully formed built-in and pre-defined library functions, but C has only few built-in functions.

The way C works is like any compiler language, you write a source code, the C program, which is human readable text. Then you call the C-Compiler and get a machine executable.

The difference is in the location where the preprocessor searches for the included file. For #include "filename" the preprocessor searches in the same directory as the file containing the directive. ... This method is normally used to include standard library header files.

Some of the advantages and direct benefits of using C in embedded systems design are as follows: Designers will not be overwhelmed by details. Designers will learn the basics of portability. Designers can reduce costs through traditional programming techniques.

"%2x" is not C code. It functions as part of a format string that is supported by the standard C printf (and scanf and others) function.

That's MIPS Assembly, one that I am not so experienced with, due to lack of hardware. But as far as I know, the ADD is adding a value, which can be an immediate, while the ADDI is explicitly adding an immediate. The difference should be, as you can see, that the immediate value in the first one is limited to 5 bits.

The main core difference between the two is that a 16 bit Microcontroller can only perform operations on 16 bit words or 2 byte word whereas the 32 bit processor can operate on 32 bits or 4byte words.

The big difference is that you know where the subroutine runs (because you call it). ... Simply, a subroutine is code you write and call as required, an interrupt is system bound and cannot be called by the user but occurs when something happens (sources are hardware, software and CPU) that requires immediate attention.

GCC does not have this. GCC's PCH mechanism (which is just a dump of the compiler memory image) is related, but is architecturally only able to read the dump back into the exact same executable as the one that produced it (it is not a structured format). Clang is much faster and uses far less memory than GCC.

So Java is both compiled as well as an interpreted language. On the other hand, C++ executes the code by using only a compiler. The C++ compiler compiles and converts the source code into the machine code. That's why c++ is faster than Java but not platform-independent.

Objective C adds syntax and semantics that allows for object oriented programming. Objective C is object oriented programming whereas, C is procedural programming. Objective C incorporates classes, whereas as C doesn't.

When you double click on an embedded object, it opens in the source program (Excel). The main differences between linked objects and embedded objects are where the data is stored and how it is updated after it is placed in the destination file.

There is no difference. You could type it as int * i if you wanted; they all mean the same thing: "i is a pointer to an int." It's the same thing. Some developers prefer the int* i notation because this way the type of i is clearly "pointer to an int" whereas int *i seems less readable.

There is no difference. int* a, b; looks as if it's declaring two pointers, when it's really doing the same thing as above. int *p, q clearly reflects p being a pointer and q not being.

Import will paste the compiled output of the header file instead of the entire code. Include will directly paste the entire header file contents and hence they are to be compiled. ... #include directive makes the compiler go to the C/C++ standard library and copy the code from the header files into the program.
