把一个字符串按某字符(分隔符)分开，如何分最好？

[cnxfmz]

	wchar_t str[] = L"111,22222";
	wchar_t strX[10] = {0};
	wchar_t strY[10] = {0};

	int strLen = wcslen(str);
	int i = 0;
	for(; i < strLen; i++)
	{
		if( str[i] == L',')
		{
			strX[i] = L'\0';
			break;
		}
		strX[i] = str[i];
	}

	int j = i + 1;
	int n =0;
	for(; j < strLen; j++)
	{
		strY[n] = str[j];
		n++;
	}

	wcout << str << endl;
	wcout << strX << endl;
	wcout << strY << endl;

只会这个笨办法，还有更方便的吗？

可以用下stl中的ostream_iterator

[就想叫yoko]

sscanf
strtok

[高性能架构探索]

给你个例子

/* 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 string\tof ,,tokens\nand some more tokens";
char seps[] = " ,\t\n";
char *token;

void main( void )
{
printf( "%s\n\nTokens:\n", string );
/* Establish string and get the first token: */
token = strtok( string, seps );
while( token != NULL )
{
/* While there are tokens in "string" */
printf( " %s\n", token );
/* Get next token: */
token = strtok( NULL, seps );
}
}


result

A string of ,,tokens
and some more tokens

Tokens:
A
string
of
tokens
and
some
more
tokens

stl中的istringstream, ostringstream只能分割空格
strtok可以自己设置token。
sscanf格式要求比较死。
