Analysis of C ++ strtok Application Methods

We will introduce the correct application method in detail in this article, hoping to help you and improve the actual program development efficiency.

The prototype of C ++ strtok is as follows:

Char * strtok (

Char * strToken,

Const char * strDelimit );

// Crt_strtok.c

/** // * In this program, a loop uses strtok

* To print all the tokens (separated by commas

* Or blanks) in the string named "string ".*/

# Include <string. h>

# Include <stdio. h>

Char string [] = "A stringtof, tokensnand some more tokens ";

Char seps [] = ", tn ";

Char * token;

Int main (void)

{

Printf ("Tokens: n ");

/** // * Establish string and get the first token :*/

Token = strtok (string, seps );

While (token! = NULL)

{/** // * While there are tokens in "string "*/

Printf ("% sn", token );

/** // * Get next token :*/

Token = strtok (NULL, seps );

}

}

C ++ strtok output:

A

String

Of

Tokens

And

Some

More

Tokens

Notes:

Strtok (char * strToken, const char * strDelimit) Where strToken and strDelimit must be in character array format. That is to say, the entry can only be the character array element address.
