如何删除目录 both in C and in C++
其中包括目录非空的情况
在Visual C++ 的include 中有direct.h
里面有rmdir的声明,我rmdir("d:\\aaa");
却提示找不到文件,这是为什么?
在C++中如何处理???
小弟先谢了

#include <stdio.h>
int remove(const char*); //成功返回0,失败返回-1
也可以用
#inclde <io.h>
int unlink(cosnt char*);//成功返回0,失败返回-1
还有:
#include <cstdlib>
using namespace std;
system("del deleted_file_direcotry_and_filename");
java与
c++
、c语言的比较文献翻译
Although it is based on
C++
, Java is more of a “pure” object-oriented language. Both
C++
and Java are hybrid languages, but in Java the designers felt that the hybridization was not as important as it was in
C++
. A hybrid language allows multiple programming styles; the reason
C++
is hybrid is to support backward compatibility with the C language. Because
C++
is a superset of the C language, it includes many of that language’s undesirable features, which can make some aspects of
C++
overly complicated.
libsvm-3.17
支持向量机源码,可在 www.csie.ntu.edu.tw/~cjlin/libsvm/ 下载到最新版本,该版本是 2013年4月更新的,3.17 版。压缩包里面有源代码和文档。以下摘自前述网站: Introduction LIBSVM is an integrated software for support vector classification, (C-SVC, nu-SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation (one-class SVM). It supports multi-class classification. Since version 2.8, it implements an SMO-type algorithm proposed in this paper: R.-E. Fan, P.-H. Chen, and C.-J. Lin. Working set selection using second order information for training SVM. Journal of Machine Learning Research 6, 1889-1918, 2005. You can also find a pseudo code there. (how to cite LIBSVM) Our goal is to help users from other fields to easily use SVM as a tool. LIBSVM provides a simple interface where users can easily link it with their own programs. Main features of LIBSVM include Different SVM formulations Efficient multi-class classification Cross validation for model selection Probability estimates Various kernels (including precomputed kernel matrix) Weighted SVM for unbalanced data Both
C++
and Java sources GUI demonstrating SVM classification and regression Python, R, MATLAB, Perl, Ruby, Weka, Common LISP, CLISP, Haskell, OCaml, LabVIEW, and PHP interfaces. C# .NET code and CUDA extension is available. It's also included in some data mining environments: RapidMiner, PCP, and LIONsolver. Automatic model selection which can generate contour of cross valiation accuracy.
