sscanf、strsep

#include <stdio.h>

#include <string.h>



int main()

{

    char token[] ="abdzxbcdefgh";

    char str[]="3:2:09";

    int a1=0, a2=0, a3=0;

    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 0;

}

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'
