arithOperationsOnVoidPointer
Best practice
Warning
Avoid arithmetic operation on void pointers
BACK TO LIST
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.
AssignmentAddressToInteger
Best practice
Warning
Assigning a pointer to an integer is not portable.
AssignmentIntegerToAddress
Security
Warning
Assigning an integer to a pointer is not portable.
CastAddressToIntegerAtReturn
Safety
Warning
Returning an address value in a function with integer return type is not portable.
CastIntegerToAddressAtReturn
Best practice
Warning
Returning an integer in a function with pointer return type is not portable.
fflushOnInputStream
Error prone
Warning
fflush() called on input stream may result in undefined behaviour on non-linux systems
invalidPointerCast
Best practice
Warning
Invalid pointer cast
memsetClassFloat
Safety
Warning
Using memset() on union which contains a floating point number.
noDestructor
Best practice
Warning
Class does not have a destructor which is recommended since it has dynamic memory/resource allocation(s).
passedByValue
Performance
Warning
Function parameter should be passed by const reference.
pointerOutOfBounds
Best practice
Warning
Undefined behaviour
postfixOperator
Performance
Warning
Prefer prefix ++/-- operators for non-primitive types.
shiftNegativeLHS
Best practice
Warning
Shifting a negative value is technically undefined behaviour
sizeofVoid
Error prone
Warning
Behaviour of 'sizeof(void)' is not covered by the ISO C standard.
stlcstrParam
Performance
Warning
Passing the result of c_str() to a function that takes std::string as argument no. 1 is slow and redundant.
stlcstrReturn
Performance
Warning
Returning the result of c_str() in a function that returns std::string is slow and redundant.
stlFindInsert
Performance
Warning
Searching before insertion is not necessary.
stlIfStrFind
Performance
Warning
Inefficient usage of string::find() in condition; string::starts_with() could be faster.
useInitializationList
Performance
Warning
Variable is assigned in constructor body. Consider performing initialization in initialization list.
uselessCallsSubstr
Performance
Warning
Ineffective call of function 'substr' because it returns a copy of the object. Use operator= instead.
varFuncNullUB
Best practice
Warning
Passing NULL after the last typed argument to a variadic function leads to undefined behaviour.
comparisonOfBoolWithBoolError
Error prone
Warning
Comparison of a variable having boolean value using relational (<, >, <= or >=) operator
rethrowNoCurrentException
Error prone
Warning
Rethrowing current exception
pureVirtualCall
Error prone
Warning
Call of pure virtual function in constructor.
