RAII-like Error Handling and Resource Management in C

Error handling and resource management are pervasive in programs. RAII originated in C++ is great. With RAII, it is much easier to write easy-to-read code that allocats/deallocats resources in the constructor/destructors. By representing a resource with a local object, we are sure that local object’s destructor will release the resource and will not forget to […]

How to Statically Link C and C++ Programs on Linux with gcc

Before statically linking you C and C++ programs, you should be aware of the drawbacks of the static linking especially with glibc. There are some good discussions already: with glibc you’re linking static programs which are not really static and some others here and here. That said, you can choose to statically link C and […]

Auto Indenting for OCaml Code in Vim with ocp-indent

The built-in indenting in Vim for OCaml seems not very good. How to set up auto indenting for OCaml code in Vim? ocp-indent works very well for me. This posts introduces how to configure Vim to use ocp-indent to automatically indent/format OCaml code. First, install ocp-indent after installing opam: $ opam install ocp-indent Second, configure […]

Java与C++在语言方面上的不同

1,Java抛弃了头文件、预处理机制、goto语句和多维数组。 2,Java不支持指针。 3,Java抛弃了联合体和结构体。 4,Java不支持独立函数。所有函数必须在类中声明。 5,Java不支持多重继承,可以使用接口模拟多重继承。 6,Java不支持运算符重载。 7,Java中布尔型不再用整数来代替。 8,Java中主函数必须有一个字符串类型的参数。 Java抛弃的C++中的这些机制和结构多数都是“危险”的,减少了语言的复杂性,增强了安全性,虽然在一定程度上减少了其灵活性。

GNU glibc Manual

“The C language provides no built-in facilities for performing such common operations as input/output, memory management, string manipulation, and the like. Instead, these facilities are defined in a standard library, which you compile and link with your programs. The GNU C library, described in this document, defines all of the library functions that are specified […]
