sscanf、strsep

#include <stdio.h>
#include <string.h> int main()
{
char token[] ="abdzxbcdefgh";
char str[]="3:2:09";
int a1=, a2=, a3=;
int ret; printf("%s\n",token);
char *tokenremain = token;
char *tok1 = strsep(&tokenremain,"cde");
printf("tok1:%s,token:%s\n",tok1,tokenremain);
tok1 = strsep(&tokenremain,"cde");
printf("tok1:%s,token:%s\n",tok1,tokenremain);
printf("%s\n", token );
ret=sscanf( str, "%d:%d:%d", &a1, &a2, &a3 );
printf( "ret=%d,%d:%d:%d\n", ret, a1, a2, a3 ); return ;
}

输出:

abdzxbcdefgh
tok1:ab,token:zxbcdefgh
tok1:zxb,token:defgh
ab
ret=3,3:2:9

注意问题:

1、sscanf返回值,是识别token的个数;

2、strsep会修改被扫描的字符串,会在扫描到的地方设置为'\0'
