sscanf函数的高级用法转载时请注明出处：http://blog.youkuaiyun.com/absurd/大家都知道sscanf是一个很好用的函数，利用它可以从字符串中取出整数、浮点数和字符串等等。它的使用方法简单，特别对于整数和浮点数来说。但新手可能并不知道处理字符串时的一些高级用法，这里做个简要说明吧。1.        常见用法。charstr[51

单子（Singleton）设计模式：在整个应用中只有一个实例存在，创建的两个实例都指向同一个对象。创建的步骤：1.构造器要私有。2.用一个私有的静态变量引用实例。3.用一个公有静态方法获得实例。如：/*  一。为什么要实现单一模式，是因为我创建的两个实例都指向同一个对象    二。要实现单一模式需要进行下面三步：     1.构造器私有     2。用一个私

Linux动态链接库.so文件的创建与使用本文以一个简单的例子，介绍linux下动态库的创建和使用操作。其中就无法找到动态库文件的问题简单介绍处理办法。动态链接库文件在windows平台下往往以.dll为后缀，而在linux平台则一般以.so为后缀，so是shared object的缩写。感觉在linux下构建动态链接库文件比在windows下省点功夫，使用gcc编译器的话，只
