若变量定义时均初始化,则会产生重定义(multiple definition)的链接错误;若某处变量定义时未初始化,则无链接错误,仅在因类型不同而大小不同时可能产生符号大小变化(size of symbol `XXX' changed)的编译警告。 在最坏情况下,编译链接正常,但不同文件对同名全局变量读写时相互影响,引发非常诡异的问题。这种风险在使用...

The integer data type in C is one of the most common data types and is represented by int. It refers to a whole number that can be either positive or negative. Although the implementation (differentcompilershave different sizes) determines the memory size of an int, they are commonly either...

We begin with a definition of a minimax estimator, Bayes estimators provide a tool for solving minimax problems. Bayes` considerations are helpful when choosing anoptimalfrequentist estimator. Viewed in this light, there is a synthesis of the two approaches. The Bayesian approach provides us with ...
LDC 是一个高性能的 D 语言编译器,依赖 DMD 作为语言前端,后端使用 LLVM 架构生成代码,在各项测试中与 C 和 C++ 性能持平,这也使得 dlang 的计算性能高于
