It saved memory to do this the expense of not being able to easily debug the program because a section of code has been overwritten with data.For a better experience, please enable JavaScript in your browser before proceeding.PS: One point I found is the way a compiler can add unnecessary (compiler-dependant) stuff in the code, while writing immediately in Assembly you can emit them.
C Program For Arithmetic Coding Revisited Synonym Code Has BeenThanks (specially to phinds whose i nsight motivated me to look up for that language ). The reason C is sometimes faster is that it is structured in a way so as to be very directly translatable into machine code whereas some other higher level languages get a bit convoluted in that translation. I remember keeping track for a while of the size of the executable for hello world. An old DOS, absolute-address version took about 15 bytes, including just the text and a single BIOS call. The C version, with relocatable code, took about 1,000 bytes. The VB.NET version, as a windows app, not a console app. Took 5,000 bytes. Just for grins I just did one as a console app under Visual Studio 2017 in VB.NET and it took 15,000 bytes but its not quite a true console app since although it puts up a DOS command box the message actually shows up in a little windows form. Still, from 15 bytes to 15,000 bytes for hello world is quite a leap. It is processor-specific which has advantages when developing a math library base component or coding CUDA threads for a PC game. A very long time ago, we had to code in either actual machine code or in assembler. So, large bunches of base code modules, originally in assembler, were grouped into libraries. C Program For Arithmetic Coding Revisited Synonym Driver Specific CodeBut now we call read() which is a library object and has lots of processor-IO driver specific code. One line equals thousands of hours of development and testing, by many people. Depending on your C compiler, it probably supports inline assembler. That feature is there because many libraries and operating systems arewere developed in C. But remember: x86, power, sparc, and other processor flavors use different assembler code. Inline only works on a single flavor of processor. Have fun. ![]() But I agree w Jim that its worthwhile to learn a little assembly just so you get the feel of programming a computer instead of programming a big fat pillow that obscures the computer from your direct vision. As an example, my boss was a fantastic assembly code programmer. He would do things like reuse the area for program initialization as a buffer for reading in data from files.
