SQL Server 2005 Integration Services (SSIS) is a new Extract, Transform, and Load (ETL) tool that ships with SQL Server 2005. As with many of Microsoft s development tools, you can extend SSIS to perform other operations not already bundled with the product. SSIS provides the SSIS Class Library for just this purpose. The SSIS Class Library Object Model includes all the classes and interfaces you need to extend or augment SSIS.

Java Regex Primer Since version 1.4, Java has had support for Regular Expressions in the core API. Java Regex follows the same basic principles used in other languages, just withdi erent access methods, and some subtledi erences with the patterns. This primer is aimed towards developers already familiar with regex in other languages wanting a brief outline of its support in Java. It may also be beneficial to developers learning regex if used in conjunction with detailed documentation explaining the construction of regex patterns. Reading the javadoc forjava.util.regex. Pattern is a must to see how the Java regex patterns aredi erent from other languages such as Perl. Most of the functions discussed herin are from thejava.util.regex. Matcher class with a few fromjava.util.regex. Pattern. Reading this text in conjunction with the javadoc of those classes is advised.

經(jīng)典C語言程序設(shè)計(jì)100例1-10 如【程序1】 題目:有1、2、3、4個(gè)數(shù)字,能組成多少個(gè)互不相同且無重復(fù)數(shù)字的三位數(shù)?都是多少? 1.程序分析:可填在百位、十位、個(gè)位的數(shù)字都是1、2、3、4。組成所有的排列后再去 掉不滿足條件的排列。 2.程序源代碼: main() { int i,j,k printf("\n") for(i=1 i<5 i++) /*以下為三重循環(huán)*/ for(j=1 j<5 j++) for (k=1 k<5 k++) { if (i!=k&&i!=j&&j!=k) /*確保i、j、k三位互不相同*/ printf("%d,%d,%d\n",i,j,k) } }
