No.
Embedded C refers to C used to program the computer in robots, microwaves, your car, etc.
C graphics is very generic and can refer to 3D rendering or just making a GUI.
Operator precedence in embedded C is exactly the same as in standard C.
C has nothing to do with graphics.
C has nothing to do with graphics.
Like C, it is used when a low-level programming language is necessary. While C++ is commonly used for graphics-heavy software such as games, photo and video editing apps, browsers, C is more widely used for embedded devices and OS kernels.
because it just doesn't
Embedded systems are made only in C as it provides efficient memory management independence
No.
In the C standard, a standalone implementation doesn't have to provide all of the library functions that a hosted implementation has to provide. The C standard doesn't care about embedded, but vendors of embedded systems usually provide standalone implementations with whatever amount of libraries they're willing to provide. and also Embedded environment, sometime, there is no MMU, less memory, less storage space. In C programming level, almost same, cross compiler do their job.
Embedded Chart
Yes, the graphics are the same, just without the 3D feature.
digital watermarks
Yes, you can install an external graphics card alongside embedded graphics. Most systems will automatically switch between the two based on the application demands, allowing you to leverage the power of the external GPU for graphics-intensive tasks while still using the integrated graphics for less demanding applications. However, it's important to ensure that your motherboard and operating system support this configuration. Additionally, you may need to adjust settings in the BIOS or operating system to optimize performance.
