c programming modulus operator floating point exception

If each part is separately being optimized then the total program will be automatically faster. First and the most important part of optimizing a computer program is to find out where to optimize, which portion or which module of the program is running slow or using huge memory. Without this point, no discussion can be started. I have mentioned all information sources in the References section at the end of this article. What I did is just make a collection of the information from various sites but mostly from that PDF file I mentioned above. I never claimed that these are my own discoveries. Also, I have modified some of them in such a way that they are almost applicable for all the environments apart from ARM. All tips of every article do not work well, so I collect only those tips together, which are very useful and very efficient. DeclarationĪctually, during my project, I have used the tips from this for optimization ARM because my project was on ARM platform, but I have also used many other articles from Internet.

So, during optimization, our motto should be to write the code in such a way that memory and speed both will be optimized. It will not be acceptable if you are programming for small device like mobiles, PDAs etc., which have strict memory restrictions. This increment in code size can also have an adverse effect on a program's complexity and readability. Often, speeding up a program can also cause the code's size to increase. In this article, I have gathered all the experiences and information, which can be applied to make a C code optimized for speed as well as memory.Īlthough a number of guidelines are available for C code optimization, there is no substitute for having a thorough knowledge of the compiler and machine for which you are programming. During a project for developing a light JPEG library which is enough to run on a mobile device without compromising quality graphics on a mobile device, I have seen and worked out a number of ways in which a given computer program can be made to run faster.
