C++完美演绎 经典算法 如 /* 头文件:my_Include.h */ #include <stdio.h> /* 展开C语言的内建函数指令 */ #define PI 3.1415926 /* 宏常量,在稍后章节再详解 */ #define circle(radius) (PI*radius*radius) /* 宏函数,圆的面积 */ /* 将比较数值大小的函数写在自编include文件内 */ int show_big_or_small (int a,int b,int c) { int tmp if (a>b) { tmp = a a = b b = tmp } if (b>c) { tmp = b b = c c = tmp } if (a>b) { tmp = a a = b b = tmp } printf("由小至大排序之后的结果:%d %d %d\n", a, b, c) } 程序执行结果: 由小至大排序之后的结果:1 2 3 可将内建函数的include文件展开在自编的include文件中 圆圈的面积是=201.0619264

The Small C compiler translates a subset of the C language into assembly language. It runs under PC/MS-DOS 2.1 and later. Small C is compatible with the Microsoft and Small Mac assemblers. Small C takes full advantage of the ability of these assemblers to generate relocatable object code, to maintain libraries of relocatable modules, and to link separately compiled program modules. It supports a small memory model with one code and one data/stack segment.

prolog 找路例子程序: === === === === === === Part 1-Adding connections Part 2-Simple Path example | ?- path1(a,b,P,T). will produce the response: T = 15 P = [a,b] ? Part 3 - Non-repeating path As an example, the query: ?- path2(a,h,P,T). will succeed and may produce the bindings: P = [a,depot,b,d,e,f,h] T = 155 Part 4 - Generating a path below a cost threshold As an example, the query: ?- path_below_cost(a,[a,b,c,d,e,f,g,h],RS,300). returns: RS = [a,b,depot,c,d,e,g,f,h] ? RS = [a,c,depot,b,d,e,g,f,h] ? no ==================================

NORTi3 is a realtime multitasking operating system conforming to the micro-ITRON 3.0 specification. NORTi3 is divided into two packages: NORTi3 Standard and NORTi3 Extended. The product NORTi3 Extended has implemented all the system calls of level E placed as "added and extended functions” in the micro-ITRON specification as well as the system calls equivalent to level X.

Most code samples included on this CD were developed with Microsoft Visual C++ version 5.0 and the Microsoft Windows CE Toolkit for Visual C++ version 5.0. The Sspi and Crypto samples were developed with Microsoft Visual C++ version 6.0 and the Microsoft Windows CE Toolkit for Visual C++ 6.0. The code in sample applications is ported for a Handheld PC, but the programming concepts that are presented apply to all Windows CE-based platforms.

光学设计软件zemax源码: This DLL models an nular aspheric surface as described in: "Annular surfaces in annular field systems" By Jose M. Sasian Opt. eng. 36 (12) P 3401-3401 December 1997 This surface is essentially an odd aspheric surface with an offset in the aspheric terms. The sag is given by: Z = (c*r*r) / (1+(1-((1+k)*c*c*r*r))^ 1/2 ) + a*(r-q)^2 + b*(r-q)^3 + c*(r-q)^4 + ... Note the terms a, b, c, ... have units of length to the -1, -2, -3, ... power.
