[問題] 把字串的前三個字元存到另一個字串
看板C_and_CPP (C/C++)作者rosemary0401 (rosemary0401)時間15年前 (2011/05/11 23:36)推噓2(2推 0噓 6→)留言8則, 4人參與討論串1/1
WCHAR *wszStr = new WCHAR[4];
wmemcpy(wszStr, L"abcde", 3);
wszStr[4] = L'\0';
//用wcout印出來確實是abc
wcout << wszStr << endl;
//但是字串比對回傳值是1，表示兩個字串不相等
int nResult = wcscmp(wszStr, L"abc");
//且刪除時會出錯
delete [] wszStr;
為什麼呢？
該如何正確的把字串的前3個字元，複製到另一個字串上呢？
