可以使用循环和条件语句来代替goto的写法，如下所示：

printf("*****************Enroll Finger Test*****************\n");
int buffer = 1;
int counts = 0;
while(buffer < 3) {
    printf("%d. Enroll: Please press finger%d......\n", buffer, buffer);
    int nRet = ZAZ_NO_FINGER;
    while(nRet == ZAZ_NO_FINGER) {
        nRet = ZAZGetImage(nhanle, DEV_ADDR);
        counts++;
        if(counts > 10000000)
            printf("wating time over......\n");
        else
            printf("wating time %d......\n", counts);
    }
    if(nRet != ZAZ_OK) {
        printf("ZAZGetImage is Fail ,errorr code = %d......\n", nRet);
        buffer = 1;
        continue;
    }
    printf("%d. ZAZGetImage ok......\n", buffer);

    nRet = ZAZGenChar(nhanle, DEV_ADDR, buffer);
    if(nRet != ZAZ_OK) {
        printf("ZAZGenChar is Fail ,errorr code = %d......\n", nRet);
        continue;
    }
    printf("%d. ZAZGenChar ok  Buffer = %d......\n", buffer, buffer);

    buffer++;
}

int nRet = ZAZRegModule(nhanle, DEV_ADDR);
if(nRet != ZAZ_OK) {
    printf("ZAZRegModule is Fail ,errorr code = %d......\n", nRet);
    goto enroll_label;
}
printf("4. ZAZRegModule ok  \n");

nRet = ZAZStoreChar(nhanle, DEV_ADDR, CHAR_BUFFER_A, 1);
if(nRet != ZAZ_OK) {
    printf("ZAZStoreChar is Fail ,errorr code = %d......\n", nRet);
    goto enroll_label;
}
printf("5. ZAZStoreChar ok  id = %d\n", 1);
