关于用while(cin>>b)与Ctrl +Z结束的问题
#include#includeusing namespace std;int main(){vectorfullname;char f;int n=0,i=1,j,k,l; //n初始应该是0,否则最后会多1while(cin.get(f)) //注意,cin会直接忽视空格,因为空格是哨兵字符,用来判断输入的截止,用get可以得到空格{fullname.push_back(f);n++; //n is the length of the word}for(vector::size_type ix=0;ixif((fullname[ix]==' ')&&(i==1)){coutfor(j=0;jcoutcouti++;continue;}else if((fullname[ix]==' ')&&(i==2)){coutfor(k=j+1;kcoutcouti++;continue;}else if(i==3){coutfor(l=k+1;lcoutcouti++;}}return 0;}

Length of instructionCollege One Semester = 46 class periods (50 min -3x week) Aug 26-Dec 10High School ? year = 90 class periods (55 min-5 x week) Conclusion: One year of high school has 4 times as much meeting time as one semester of college. Thus high school students can learn and internalize the foreign language structures easier because they have more time to use the language. True high school students can be silly and not motivated but the mere fact that they have four times as much time on task means they can learn much more vocabulary and practice using this. (TPRS shows this)In 4-5 years of high school a student can achieve a speaking fluency with correct pronunciation that a similar college student could not learn in 2-3 years.Methods of InstructionCollege Thus colleges cannot imitate high school methods, they have a limited amount of time to work with. What can colleges do? 1. Recognize the wealth of vocabulary that the high school student brings with him even if he can't use the Dative Case properly.2. Review the fundamentals of the grammar. (High School students are taught structures and often very little grammar) But don't kill the enthusiasm with endless drills of adjective endings and exceptions to the rule.3. Do longer readings for fluency, but not a philosophical works where the students have to look up every other word.4. Polish the writing style by assigning regular writing tasks which build on what the students know, while practicing the more complicated sentence structures.5. Build on the speaking proficiency started in high school. (If a student begins the college class without any previous German he can still learn quickly based on his French or Spanish background) The article in Unterrichtspraxis says students continue German in college because “they loved the experience of German in high school.” This means the felt successful. This feeling of success is important in the college class.High SchoolWhat should continuing high school students should bring to college classes? 1. Knowledge of basic vocabulary and the ability to use it.2. The ability to use correct verb endings in present tense3. The ability to use the Perfekt tense to talk about the past.4. The ability to use correct word order in simple and complex sentences.5. The genders of some basic words.

回答者: 用心帮助您 - 高级经理 六级 2-22 13:46 Dictionaries range broadly in purpose, size, and price; and choosing one is a very personal decision. The best advice is to make note of the things you and your family look up in a dictionary over a few weeks' time, and then go to a comprehensive bookstore to make the choice. Here are a few things to look for in making your selection. Size Big, complete (unabridged) dictionaries are expensive and take a lot of room in your office or home. They are also difficult for children to use because they are bulky, and it takes longer to look something up because new readers' alphabetizing skills are incomplete. An unabridged dictionary on the coffee table might impress your friends; but unless you use a dictionary on a daily basis, it probably is not a good buy. Perhaps you should look at smaller "college" dictionaries. Pronunciation guide Many people use a dictionary to help them pronounce new words. (One caller to the hot line saw an "etagere" advertised for sale, knew what it was and wanted one, but didn't want to call the seller without knowing how to pronounce the word.) The pronunciation guide should be complete but not contain a lot of unfamiliar symbols that require continual cross-checking--especially with the vowels. The English vowel system is complex because we use one letter to spell many different sounds. For example, the letter A has three different sounds in the words at, age, and art. The job for the dictionary makers is to find three common symbols to represent the different pronunciations. Examples Sample sentences showing common uses of words are very helpful, both in clarifying the meaning and helping the reader remember the word. The words in the sentences should not be any more difficult than the target word, however, or the reader is sent off on a frustrating chase through the dictionary. In the words of technology, "A good dictionary should be user-friendly." Usage Notes Many dictionaries comment on the usage of words in different types of situations. Many of the old dictionaries contained only the standard accepted usages. "Ain't" was not to be found and teachers could correct their charges by saying, "Ain't isn't in the dictionary." Imagine the teachers' dismay when dictionaries started including such forms! The dictionaries do comment on the usage--non-standard, colloquial, regionalism are some of the terms used to let readers make their own decisions as to whether they want to use the term. One final comment--forms of speech change much more rapidly than written forms; and many spoken items never make it to the written language (slang, for example). For this reason, you will need to buy several dictionaries during your reading life. Find one that you like, and consider its new editions when it's time for a new one.
IndexOf小问题,求大牛~~~~
方法一,如一楼用IndexOf方法二,分割字符串:string fullPath = "我的电脑\\HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft";char[] splitChar = "\\".ToCharArray();string[] pathArray = fullPath.Split(splitChar);int SecondIndex = pathArray[0].Length + pathArray[1].Length + 2; 方法三(麻烦),string fullPath = "我的电脑\\HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft";char[] pathChar = fullPath.ToCharArray();int cnum=0;int index = 0;foreach (char c in pathChar){if(index<3){if(c=='\')cnum++;index++;}else{break;}}还有类似于SubString+IndexOf等等方法。
另外你既然谈到正则表达式,我就解释一下为什么不用正则表达式。
正则表达式是需要逐字进行匹配的方法,你这里如果要用,无非就是去在每个"\\"的间隔之间,匹配任意个除"\\"的任意字符,最后为了取得索引,还是必须计算间隔之间的长度。
而其意义,无非就是我给你写出的第二种方法
