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.
passedByValue
Performance
Warning
Function parameter should be passed by const reference.
pointerPositive
Performance
Informational
A pointer can not be negative so it is either pointless or an error to check if it is not.
postfixOperator
Performance
Warning
Prefer prefix ++/-- operators for non-primitive types.
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.
