Description: 枚举法(穷举法)
“笨人之法”: 把所有可能的情况一一测试,筛选出符合条件的各种结果进行输出。
【例一】百元买百鸡:用一百元钱买一百只鸡。已知公鸡5元/只,母鸡3元/只,小鸡1元/3只。
分析:
这是个不定方程——三元一次方程组问题(三个变量,两个方程)
x+y+z=100
5x+3y+z/3=100
设公鸡为x-enumeration method (exhaustive) "Benren Regulation" : all possible test of January 1, and selected eligible for the results output. Cases -- 100 yuan to buy a 100 chicken : 100 yuan to buy 100 chickens. Known rooster 5 yuan / only, the hen 3 yuan / only and chicken one yuan / 3. Analysis : This is a volatile equation -- Group 3 linear equation (3 variable, equation 2) x + y + z = 100 5x +3 y + z / 3 = 100 x located rooster

Description: volatile的作用volatile的本意是“易变的”
由于访问寄存器的速度要快过RAM,所以编译器一般都会作减少存取外部RAM的优化。比如:
-The role of volatile volatile are intended to be " volatile" registers as faster access than RAM, so the compiler will generally be optimized to reduce access to external RAM. For example:

Description: 就象大家更熟悉的const一样,volatile是一个类型修饰符(type specifier)。它是被设计用来修饰被不同线程访问和修改的变量。如果没有volatile,基本上会导致这样的结果:要么无法编写多线程程序,要么编译器失去大量优化的机会。-Like everyone, like more familiar const, volatile is a type modifier (type specifier). It is modified by different threads designed to access and modify the variables. If you do not volatile, essentially lead to this result: either can not write multi-threaded program, or lose a lot of compiler optimization opportunities.
