你曾经想要计算您的代码在 C 或 c + + 没有评注中的行和空行，好有了这个程序，你可以做到。请随意投票或活着一些评论，它将非常感激 ！

利用Gauss积分公式进行数值积分，将区间 细分成n个相等的子区间，然后在每个上使用经过修改适用于不同子区间的三点Gauss公式计算积分的值，然后求和。-Using Gauss integral formula for numerical integration, will be subdivided into n-equal interval sub-intervals, and then apply to each use of a modified three-point range in different sub-Gauss formula to calculate the value of points, and then summed.

应用背景STL = STL文件，一种3D模型文件格式STL（STereo Lithography的缩写） STL文件格式是由3D SYSTEMS 公司于1988 年制定的一个接口协议，是一种为快速原型制造技术服务的三维图形文件格式。STL 文件由多个三角形面片的定义组成，每个三角形面片的定义包括三角形各个定点的三维坐标及三角形面片的法矢量。三角形顶点的排列顺序遵循右手法则。 STL 文件有2 种类型：文本文件(ASCII格式)和二进制文件(BINARY)。关键技术This program may crash your system or run poorly depending on your   hardware.  The program and code contained in this archive was scanned   for virii and has passed all test before it was put online.  If you   use this code in project of your own, send a shout out to the author!

随着人类基因组计划的实施，通过基因组测序，蛋白质序列测定结构解析等实验，分子生物学家提供了大量的有关生物分子的原始数据，需要利用现代计算技术对这些原始数据进行收集、整理、管理以便于检索使用。而为了解释和理解这些数据，还需要对数据进行比对、分析，建立计算模型，进行仿真、预测与验证，因而出现生物信息学，它的出现，极大的促进了分子生物学的发展。-With the human genome project implementation, through genome sequencing, protein sequencing experiments such as structural analysis, molecular biologists to provide a large amount of biological molecules of the original data, the need to use modern technology to these raw data collection, collation and management in order to facilitate retrieval use. To explain and understand these data, and data need to be compared to analysis, model, simulation, prediction and validation, therefore, bioinformatics, and its emergence has greatly promoted the development of molecular biology.

一些C编程语言经典编程题目，希望对大家有用。#include int main(void) { unsigned int i = 0x12345678; char*pc =(char*)&i; printf("0x%x ", *pc); double *pd = (double*)&i; printf("%f ", *pd); printf("sizeof pc = %d sizeof pd = %d ", sizeof(pc), sizeof(pd)); return 0; }
