《C程序设计语言》是由C语言的设计者Dennis M. Ritchie和著名计算机科学家Brian W. Kernighan编写的一部介绍标准C语言及其程序设计方法的权威性经典著作。全面、系统地讲述了C语言的各个特性及程序设计的基本方法，包括基本概念、类型和表达式、控制流、函数与程序结构、指针与数组、结构、输入与输出、UNIX系统接口、标准库等内容。

Gmsh is an open source 3D finite element mesh generator with a built-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface, in ASCII text files using Gmsh"s own scripting language (.geo files), or using the C++, C, Python or Julia Application Programming Interface (API).
