#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‘
