c encoding extracts words from a sentence where the sentence is entered by the user himself

string str="tom,how do you do?";

Convert all punctuation points to spaces.

str=","," ").replace("."," ").

replace("?"," ").replace(";"," ").

replace(":","");

string results=' ');

for(int i=0;i<;i++)

if(results[i].trim()!="")conwirte(results[i]);

Not tested.

static void main(string args)"The reversed English sentence is:" + result);

Arrays are swapped for the first and last ones, and so on.

With split(' ') to cut the sentence into words.

Start by storing the words in the array.

It is then read out using a foreach loop. Add spaces when reading.

Use the substring. References give. It's time for the landlord to brush up on the basics.

Let's use the regular . It can be divided into more fine.

du。And not just based on spaces. Also zhi can be based on punctuation ah of the dao and the like. Hehe. References.

Take the following ** under the right to test:

Put "hello, how are you!"."Split into 4 words.

static void main(string args)}

Just use the lookup method and output this sentence.

Create a dictrory that stores words with the number of words.

Then each time the insertion is made, "Word."",1, if the insertion fails, it proves that it already exists, and the value can be increased by 1.

hashtable hashtable = new hashtable();

char charseparators = new char ;All word separators are enumerated here.

Here, the sentence is split into words and the blank elements are removed.

string words = "aaa bbb aaa ccc ddd,eee,edc.".split(charseparators, ;

for (int i = 0;i < i++) loop, just output the contents of the hashtable.

It is impossible not to open up new memory space, strings are immutable objects, if you want to generate new strings, you must open up new memory, you can first split the string by comma, invert a single word, and then use a comma to connect the string.

public static void main(string args)

if (";"))

/ scanner.

The number of words is:" + dc);

The number of letters is:" + zc - 1));

The number of sentences is:" + jc);
