| V563 | It is possible that this 'else' branch must apply to the previous 'if' statement. | EXP19-C |
| V564 | The '&' or '|' operator is applied to bool type value. You've probably forgotten to include parentheses or intended to use the '&&' or '||' operator. | EXP46-C |
| V566 | The integer constant is converted to pointer. Possibly an error or a bad coding style. | INT36-C |
| V567 | The modification of a variable is unsequenced relative to another operation on the same variable. This may lead to undefined behavior. | EXP30-C |
| V568 | It's odd that the argument of sizeof() operator is the expression. | EXP44-C, ARR01-C |
| V569 | Truncation of constant value. | INT31-C |
| V573 | Uninitialized variable 'Foo' was used. The variable was used to initialize itself. | EXP33-C, EXP53-CPP |
| V574 | The pointer is used simultaneously as an array and as a pointer to single object. | EXP08-C |

| V593 | Consider reviewing the expression of the 'A = B == C' kind. The expression is calculated as following: 'A = (B == C)'. | EXP00-C |
| V594 | The pointer steps out of array's bounds. | ARR30-C |
| V595 | The pointer was utilized before it was verified against nullptr. Check lines: N1, N2. | EXP34-C |
| V596 | The object was created but it is not being used. The 'throw' keyword could be missing. | MSC13-C |
| V597 | The compiler could delete the 'memset' function call, which is used to flush 'Foo' buffer. The RtlSecureZeroMemory() function should be used to erase the private data. | MSC06-C |
| V598 | The 'memset/memcpy' function is used to nullify/copy the fields of 'Foo' class. Virtual table pointer will be damaged by this. | EXP62-CPP, OOP57-CPP |
| V599 | The virtual destructor is not present, although the 'Foo' class contains virtual functions. | OOP52-CPP |

| V615 | An odd explicit conversion from 'float *' type to 'double *' type. | FLP34-C |

| V619 | An array is being utilized as a pointer to single object. | EXP08-C |
| V620 | It's unusual that the expression of sizeof(T)*N kind is being summed with the pointer to T type. | EXP08-C |

| V634 | The priority of the '+' operation is higher than that of the '<<' operation. It's possible that parentheses should be used in the expression. | EXP00-C |
| V635 | Consider inspecting the expression. The length should probably be multiplied by the sizeof(wchar_t). | MEM35-C |

| V641 | The buffer size is not a multiple of the element size. | EXP36-C |
| V642 | Saving the function result inside the 'byte' type variable is inappropriate. The significant bits could be lost breaking the program's logic. | INT31-C |
| V643 | Unusual pointer arithmetic. The value of the 'char' type is being added to the string pointer. | ARR30-C, EXP08-C |
| V645 | The function call could lead to the buffer overflow. The bounds should not contain the size of the buffer, but a number of characters it can hold. | ARR30-C, STR31-C |
| V647 | The value of 'A' type is assigned to the pointer of 'B' type. | INT36-C |
| V648 | Priority of the '&&' operation is higher than that of the '||' operation. | EXP00-C |
| V649 | There are two 'if' statements with identical conditional expressions. The first 'if' statement contains function return. This means that the second 'if' statement is senseless. | MSC12-C |
| V650 | Type casting operation is utilized 2 times in succession. Next, the '+' operation is executed. Probably meant: (T1)((T2)a + b). | EXP08-C |

| V675 | Writing into the read-only memory. | STR30-C, ENV30-C |
| V679 | The 'X' variable was not initialized. This variable is passed by a reference to the 'Foo' function in which its value will be utilized. | EXP33-C, EXP53-CPP |
| V681 | The language standard does not define an order in which the 'Foo' functions will be called during evaluation of arguments. | EXP10-C |
| V687 | Size of an array calculated by the sizeof() operator was added to a pointer. It is possible that the number of elements should be calculated by sizeof(A)/sizeof(A[0]). | EXP08-C |
| V688 | The 'foo' local variable possesses the same name as one of the class members, which can result in a confusion. | DCL01-C |
| V689 | The destructor of the 'Foo' class is not declared as a virtual. It is possible that a smart pointer will not destroy an object correctly. | OOP52-CPP |
| V692 | An inappropriate attempt to append a null character to a string. To determine the length of a string by 'strlen' function correctly, a string ending with a null terminator should be used in the first place. | STR32-C |
| V694 | The condition (ptr - const_value) is only false if the value of a pointer equals a magic constant. | ARR30-C |
| V695 | Range intersections are possible within conditional expressions. | MSC01-C |

| V698 | strcmp()-like functions can return not only the values -1, 0 and 1, but any values. | EXP12-C |
| V699 | Consider inspecting the 'foo = bar = baz ? .... : ....' expression. It is possible that 'foo = bar == baz ? .... : ....' should be used here instead. | EXP45-C |
| V701 | realloc() possible leak: when realloc() fails in allocating memory, original pointer is lost. Consider assigning realloc() to a temporary pointer. | WIN30-C, MEM51-CPP |
| V703 | It is odd that the 'foo' field in derived class overwrites field in base class. | DCL01-C |
| V705 | It is possible that 'else' block was forgotten or commented out, thus altering the program's operation logics. | EXP19-C |
| V708 | Dangerous construction is used: 'm[x] = m.size()', where 'm' is of 'T' class. This may lead to undefined behavior. | EXP50-CPP |
| V709 | Suspicious comparison found: 'a == b == c'. Remember that 'a == b == c' is not equal to 'a == b && b == c'. | EXP13-C |
| V711 | It is dangerous to create a local variable within a loop with a same name as a variable controlling this loop. | DCL01-C |
| V712 | Be advised that compiler may delete this cycle or make it infinity. Use volatile variable(s) or synchronization primitives to avoid this. | MSC06-C |
| V713 | The pointer was utilized in the logical expression before it was verified against nullptr in the same logical expression. | EXP34-C |

| V789 | Iterators for the container, used in the range-based for loop, become invalid upon a function call. | CTR53-CPP |
| V796 | A 'break' statement is probably missing in a 'switch' statement. | MSC17-C |
| V797 | The function is used as if it returned a bool type. The return value of the function should probably be compared with std::string::npos. | EXP12-C |
