Big Data is focused on the analysis of data mining through the computer, in the vocational skills test will be examined in some programming language, will involve the relevant knowledge of the C language.

C is a process-oriented, abstract, general-purpose programming language that is widely used in low-level development.C can be compiled and processed in a simple way with low-level memory.C is an efficient programming language that produces only a small amount of machine language and does not require any runtime support to run.

While C offers many low-level processing features, it remains cross-platform, and C programs written to a standard specification can be compiled on many computer platforms, including platforms such as embedded processors and supercomputers.
