Among various computer programming languages, C is the most basic and widely used language. It gives maximum efficiency and control to the programmers. The C language can be used for mathematical operations ranging from additions and subtractions to square roots and cube roots, alogn with other polynomial powers that can be created through C programming. If you want to write mathematical programs which involve floating points and so on then you will need access to the mathematics library.
