1. 解释错误消息"iso c++ forbids converting a string constant to char*"的含义 该错误消息表示,在ISO C++标准中,禁止将字符串常量(string constant)直接转换为char*类型的指针。字符串常量在内存中通常是存储在只读区域的,而char*类型的指针通常被用来指向可以修改的字符数组。因此,允许这种转换可能会导致未定义行...

IntStream intStream1 = testString.codePoints(); We need to map the returned IntStream to Stream<Character> to display it to users: Stream<Character> characterStream2 = testString.codePoints().mapToObj(c -> (char) c); 4. Conversion to a Stream of Single Character Strings So far, we...
(2) CString转换成char* 若将CString类转换成char*(LPSTR)类型,常常使用下列三种方法: 方法一,使用强制转换。例如: CString theString( (_T("Char test ")); LPTSTR lpsz =(LPTSTR)(LPCTSTR)theString; 1. 2. 方法二,使用strcpy。例如: CString theString( (_T("Char test ")); ...
会跳出警告:warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings] 改成下面会通过warning char* p = (char*)"abc"; // OK 或者改成下面: charconst*p ="abc"; // OK 原因解析: 我们在学习c或者c++的时候都知道,如果在赋值操作的时候,等号两边的变量类型不一样,那么...
