VS2017-VC++校验和计算小工具

發布時間：2025/3/21 c/c++ 36 豆豆

生活随笔收集整理的這篇文章主要介紹了 VS2017-VC++校验和计算小工具小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

運行界面如下：

輸入格式要求：必須是ascii代表數字的字符（0-F，大小寫不限)，必須成雙，可以有空格。

主要代碼：

CMFCApplicationBleApAnalogDlg::CMFCApplicationBleApAnalogDlg(CWnd* pParent /*=nullptr*/)
?? ?: CDialogEx(IDD_MFCAPPLICATIONBLEAPANALOG_DIALOG, pParent)
?? ?, m_edit1_data(_T(""))
