}邮件地址判断,如下:
TCHAR buf1[12] = { 0 };
TCHAR buf2[12] = { 0 };
TCHAR buf3[12] = { 0 };
int ret = swscanf_s(_T("abc2018@QQ.com"),
_T("%[a-zA-B0-9] %*[@] %[a-zA-Z]%*[.]%s"),
buf1, 12,buf2,12,buf3,12);
TRACE(_T("ret=%d: %s %s %s\n"),ret, buf1,buf2,buf3);
if (ret == 3)
TRACE(_T("正确的邮件地址"));
else
TRACE(_T("不正确的邮件地址"));
