求大神解答 而且還有型別不兼容怎么搞啊，是不是我哪里寫錯了，新人用VS遇到好多問題，急求！！

.c 檔案 一般變數宣告要放到函式中的一個執行陳述句之前， 可以把檔案改為.cpp C++可以隨時宣告 隨時使用推薦使用TCHAR LPCTSTR LPTSTR 和 _t _st 帶 t 的函式, 可以使用UNICODE 和 非UNICODE 的編譯環境

放在一個{
}
里
{
char a[ 0x40 ];
a做點什么事

我為什么會出現這種情況啊，無法打開源檔案，如果不加這一個，那下面的case WM—CHAR中的sprintf就會出錯

你工程默認用的是unicode 但你在專案中實際用多位元組型別,造成不兼容uj5u.com熱心網友回復：
2樓正解C語言switch case的代碼塊需要{}，C++的話隨意switch (uMsg)
{
case WM_CHAR:
{
char szChar[20];
sprintf(szChar, "char code is %d", wParam);
MessageBox(hwnd, szChar, "char", 0);
break;
}
。。。
}

case的代碼塊 中 如果 定義變數 必須 要 {}轉載請註明出處，本文鏈接：https://www.uj5u.com/gongcheng/16895.html
