accessMoved
Best practice
Error
Access of moved variable.

C / C++ rules
C and C++ are really performant languages and can be very error-prone. We all had core dumps and made pointer arithmetic errors! Thankfully, Codiga has hundreds of static analysis rules to flag potential errors in your C/C++ code, automate code reviews and merge with confidence.
allocaCalled
Best practice
Error
Obsolete function 'alloca' called. In C99 and later it is recommended to use a variable length array instead.
arrayIndexOutOfBoundsCond
Best practice
Error
Array access out of bounds with a conditions
asctime_sCalled
Best practice
Error
Obsolete function 'asctime_s' called. It is recommended to use 'strftime' instead.
assertWithSideEffect
Best practice
Error
Assert statement calls a function which may have desired side effects: 'IsAddressInSegment'.
assignmentInAssert
Best practice
Error
Assert statement modifies variable
compareBoolExpressionWithInt
Best practice
Error
Comparison of a boolean expression with an integer other than 0 or 1.
constStatement
Best practice
Error
Detect unused variables
derefInvalidIteratorRedundantCheck
Best practice
Error
Condition is redundant or value is derefenced
exceptThrowInDestructor
Best practice
Error
Catching exception in destructor
funcArgOrderDifferent
Best practice
Error
Function not called with the right arguments
getsCalled
Best practice
Error
Obsolute function gets() called
identicalConditionAfterEarlyExit
Best practice
Error
Identical condition and return expression
identicalInnerCondition
Best practice
Error
Identical inner 'return' condition is always true.
ignoredReturnValue
Best practice
Error
Return value not used
incorrectLogicOperator
Best practice
Error
Logical conjunction always evaluates to false
integerOverflowCond
Best practice
Error
Integer overflow with condition
invalidLengthModifierError
Best practice
Error
Format string conversion error
invalidPrintfArgType_float
Best practice
Error
Invalid formatter for float
invalidPrintfArgType_sint
Best practice
Error
Invalid formatter for signed long long
invalidPrintfArgType_uint
Best practice
Error
Invalid formatter for unsigned int
invalidscanf
Best practice
Error
Invalid scanf
invalidScanfArgType_int
Best practice
Error
Invalid scanf for int
invalidTestForOverflow
Best practice
Error
Invalid test for overflow
literalWithCharPtrCompare
Best practice
Error
Direct string comparison. Compare with strcmp() instead
mismatchingContainerExpression
Best practice
Error
Iterators to containers from different expressions
negativeIndex
Best practice
Error
Negative index access
noCopyConstructor
Best practice
Error
Class does not have a copy constructor which is recommended since it has dynamic memory/resource allocation(s).
noOperatorEq
Best practice
Error
Class does not have a operator= which is recommended since it has dynamic memory/resource allocation(s).
nullPointerArithmeticRedundantCheck
Best practice
Error
Either the condition is redundant or there is overflow in pointer subtraction.
nullPointerRedundantCheck
Best practice
Error
Either the condition is redundant or there is possible null pointer dereference
objectIndex
Best practice
Error
The address of local variable might be accessed at non-zero index.
operatorEqToSelf
Best practice
Error
operator=' should check for assignment to self to avoid problems with dynamic memory.
operatorEqVarError
Best practice
Error
Member variable is not assigned a value
oppositeInnerCondition
Best practice
Error
Opposite inner 'return' condition leads to a dead code block.
pointerSize
Best practice
Error
Size of pointer used instead of size of its data.
redundantAssignInSwitch
Best practice
Error
Variable is reassigned a value before the old one has been used
seekOnAppendedFile
Best practice
Error
Repositioning operation performed on a file opened in append mode has no effect.
selfAssignment
Best practice
Error
Redundant assignment of variable to itself.
signConversion
Best practice
Error
Expression can have a negative value. That is converted to an unsigned value and used in an unsigned calculation.
sizeofCalculation
Best practice
Error
Calculation inside sizeof().
sizeofDivisionMemfunc
Best practice
Error
Division by result of sizeof(). memset() expects a size in bytes
staticStringCompare
Best practice
Error
Unnecessary comparison of static strings.
uninitMemberVar
Best practice
Error
Member variable not initialized in the constructor.
uninitMemberVarPrivate
Best practice
Error
Member private variable is not initialized in the constructor.
uselessAssignmentPtrArg
Best practice
Error
Assignment of function parameter has no effect outside the function. Did you forget dereferencing it?
uselessCallsEmpty
Best practice
Error
Ineffective call of function 'empty()'. Call 'clear()' instead.
virtualCallInConstructor
Best practice
Error
Dynamic binding is not used.
mismatchingBitAnd
Best practice
Error
Mismatching bitmasks.
returnStdMoveLocal
Best practice
Error
Using std::move for returning object by-value from function will affect copy elision optimization
