Such a statement will cause the function to return to the caller when the return statement is executed (before the function would otherwise return to the caller, hence, early). Suspicious explicit type casting. Passing cheap-to-copy argument by reference may lead to decreased performance. AUTOSAR. By clicking Sign up for GitHub, you agree to our terms of service and V1025. String is printed into itself. V818. V3049. The constant NN is being utilized. If function ends without return (or throw), then the behaviour of the program will be undefined. The line contains control character 0x0B (vertical tabulation). This may lead to undefined behavior. V571. V592. V2501. V3021. V3181. Every switch-clause should be terminated by an unconditional 'break' or 'throw' statement. The '//' and '/*' character sequences should not appear within comments. Explicit conversion from memsize type to 32-bit integer type. OWASP. Function always returns the same value of NN. The 'x' variable is assigned values twice successively. Microsoft-specific: In the Microsoft C implementation, the long long type is large enough to hold the product of two int values without overflow. String literal is identical to variable name. V3510. V577. The reference was used before it was verified against null. Email? The expression is incorrect or it can be simplified. V3140. The analysis results could be incomplete. Member 'x' should point to string terminated by two 0 characters. This may lead to undefined behavior. Destructor of the object will be invoked a second time after leaving the object's scope.

The 'static' storage class specifier should be used in all declarations of functions that have internal linkage. Unsafe invocation of event, NullReferenceException is possible. Consider using a comparison with defined precision: Math.Abs(A - B) < Epsilon or Math.Abs(A - B) > Epsilon.

An identifier with array type passed as a function argument should not decay to a pointer. Copying from potentially tainted data source. Verifying that a pointer value is not NULL is not required. Suspicious comparison found: 'a == b == c'. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. [Serializable] attribute is missing. Constructor contains potentially uninitialized members. Consider inspecting the 'Foo' function call. Youll need to comment out this line of code in order to make your code compile. V2510. InvalidClassException may occur during deserialization. Variables are initialized through the call to the same function. Defining absolute path to file or directory is considered a poor coding style. In lieu of a data type, void functions use the keyword "void." A void function performs a task, and then control returns back to the caller--but, it does not return a value. V643. V542. V786. A write outside the bounds of this variable may occur. V1042. Parameter of 'std::stop_token' type is not used inside function's body. Consider assigning the seed to a value not known at compile-time. V3133. Is that what you want? V3141. MISRA. Variable was used as a divisor before it was compared to zero. and '.' Possible missing parentheses. No return statement is required. V6081. The 'malloc' function allocates suspicious amount of memory calculated by 'strlen(expr)'. MISRA. V3047. V002. Dangerous explicit type pointer conversion. V665. V784. Microsoft-specific: The Microsoft C implementation returns the expression value to the process that invoked the program, such as cmd.exe.
