A value of integral or enumeration type to a pointer (从整形或者enum枚举类型转换为指针) A pointer to a function to a pointer to a function of a different type (从指向函数的指针转向另一个不同类型的指向函数的指针) A pointer to an object to a pointer to an object of a different type (...
V613. Suspicious pointer arithmetic with 'malloc/new'. V614. Use of 'Foo' uninitialized variable. V615. Suspicious explicit conversion from 'float *' type to 'double *' type. V616. Use of 'Foo' named constant with 0 value in bitwise operation. V617. Argument of the '|' bitwise opera...
The reinterpret_cast operator allows any pointer to be converted into any other pointer type. It also allows any integral type to be converted into any pointer type and vice versa. Misuse of the reinterpret_cast operator can easily be unsafe. Unless the desired conversion is inherently low-level...
typedef void (*FunctionPointer)(int); int value = 21; const int* pointer =&value;//int * pointer_r = reinterpret_cast<int*>(pointer); // Error: reinterpret_cast from type 'const int*' to type 'int*' casts away constness FunctionPointer funcP = reinterpret_cast<FunctionPointer>(pointer...

The analyzer has detected a pointer cast from one type to another, which leads to undefined behavior. Objects of different types may be aligned differently, and casting a pointer type may break the...
