The '?.' Expression of sizeof(T)*N kind is summed up with pointer to T type. An odd precise comparison. Consider inspecting this expression. V3027. Pointer to an object of the class is cast to unrelated class. Size of every element in X array is not equal to divisor. Two or more case-branches perform the same actions. Expression of the 'A - B > 0' kind will work as 'A != B'. V3059. V3160. These conditions may be true or false. The expression of strlen(MyStr.c_str()) kind can be rewritten as MyStr.length(). How to Make a Black glass pass light through it? Expression is enclosed by parentheses twice: ((expression)). Extracting arguments from a list of function calls. V6080. Both operands of an operator should be of the same type category. This value is already assigned to the 'b' variable. . Not the answer you're looking for? MISRA. V2552. V6074. Classes should always be derived from std::exception (and alike) as 'public'. This variable is passed by reference to the 'Foo' function in which its value will be used. V636. V770. V5012. There should be no implicit integral-floating conversion. Parts of an SQL query are not delimited by any separators or whitespaces. Note that throw_blah is the weird bit, not foo. Possible excessive expression or typo. V5301. The expression contains a suspicious mix of integer and real types. Fixing "no return statement in function returning non-void" and warning Possible error in program's logic. V586. V3182. All analyzer messages were filtered out or marked as false positive. V2592. It is possible that different variables are used inside initializer and iterator. Its representation is implementation-defined. V3101. warning: non-void function does not return a value Naimur Rahman 44 subscribers Subscribe 1 Share 316 views 6 months ago warning: non-void function does not return a value Show more Show more. MISRA. Decreased performance. Unchecked tainted data is used in expression. V3034. The 'goto' statement shouldn't jump to a label declared earlier. Consider inspecting it. V6046. It is possible that the 'i' variable should be incremented instead of the 'n' variable. V1033. V615. A boy can regenerate, so demons eat him for years. V568. V6100. Consider replacing this function with 'std::uncaught_exceptions'. MISRA. MISRA. V3143. If the function has a return type other than void, it's a serious bug, and the compiler prints a warning diagnostic message. As a good engineering practice, always specify a return type for your functions. This means that the second 'if' statement is senseless. Two identical text blocks were detected. Inspect the Nth argument. A pointer without owner is added to the container by the 'emplace_back' method. V3024. InvalidClassException may occur during deserialization. Use _beginthreadex/_endthreadex functions instead of CreateThread/ExitThread functions. V2587. V2616. V1093. V605. Consider inspecting usage of 'Y' counter. Any label should be declared in the same block as 'goto' statement or in any block enclosing it. V511. Use 'memmove' function. The assignment to a member of the readonly field will have no effect when the field is of a value type. MISRA. V662. An alternative would be to have the default setting of Wreturn-type depend on flag_isoc99. Then the ',' operator returns a resulting value from the right side of the expression. V824. V3517. V630. Call of 'std::is_constant_evaluated' function always returns the same value. AUTOSAR. V204. Consider inspecting the 'for' operator. Modification of variable is unsequenced relative to another operation on the same variable. Expression containing increment (++) or decrement (--) should not have other side effects. Consider inspecting the expression. V1054. Then the return statement is executed, returning the value of 5 back to the caller. V3551. An exception handling block does not contain any code. Possible incorrect initialization of variable. This leads to undefined behavior. The compiler may issue a warning diagnostic message about unreachable code if it finds any statements placed after the return statement. MISRA. g++ How to get warning on ignoring function return value By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Consider inspecting the NN argument of the 'Foo' function. V6051. More than one sizeof() operator is used in one expression. Variable is not passed into foreach loop by reference, but its value is changed inside of the loop. The '||' operator is surrounded by opposite expressions 'x' and '!x'. The 'static' storage class specifier should be used in all declarations of functions that have internal linkage. V6078. Consider inspecting the expression. V787. V2008. The expression is excessive or contains a misprint. Replace iterator++ with ++iterator. I forgot it would still issue if all paths don't have a return. Function receives an odd argument. V3047. V1031. The passed line may contain format specification. V108. An example of data being processed may be a unique identifier stored in a cookie. The second function call to function printHi() wont even compile. Due to the way the compiler is constructed, warnings are generally reported early, and suppressing this warning based on later analysis would be difficult. 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. V205. V3149. V2617. Consider assigning value to 'foo' variable instead of declaring it anew. V2609. An exception handling block does not contain any code. V2549. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. nlohmann/json.hpp:11996:5: warning: non-void function does not return a value in all control paths [-Wreturn-type], static ReferenceType get_ref_impl(ThisType& obj) V2568. V3122. An array/object was declared but was not utilized. Unsafe usage of the 'bool' and integer types together in the operation '&='. It will be closed before the method exits. Signed value is converted to an unsigned one with subsequent expansion to a larger type in ternary operator. V3520. Arguably, this is a shortcoming in the compiler. Assign the value to the Function procedure name and then perform the End Function statement. The function is deprecated in the Win64 system. Consider restricting the type parameter to reference types. A write outside the bounds of this variable may occur. V700. V6015. Decreased performance. Variable should be declared in a scope that minimizes its visibility. V520. V823. Memory allocation will lead to an exception. Locking operations must be performed on the same thread. V782. V5305. V3161. Dangerous call of 'Foo' function. V703. Function printHi has a void return type, meaning it doesnt return a value. @Sneftel Good point. Expression resulting from the macro expansion should be surrounded by parentheses. Negative value is implicitly converted to unsigned integer type in arithmetic expression. This will cause the loss of the higher bits. Some diagnostic messages may contain incorrect line number. Use of '\0xNN' characters. V806. V6045. The code can be rewritten as either: Although you report testing the former option, GCC will not report the warning in this case, so I believe your test was faulty, such as compiling code other than what you intended to compile. Undefined behavior. V713. V2582. The 'delete' operator is applied to non-pointer. So GCC knows there is no possible control path that does not return a value, but it reported the warning (elevated to an error) anyway. The operator evaluates both operands. V749. Recurrent serialization will use cached object state from first serialization. Object is used as an argument to its own method. The 'then' statement is equivalent to the 'else' statement. What if I write return statement in constructor? V529. There should be no attempt to write to a stream that has been opened for reading. The 'throw' keyword could be missing. The field will have default value on different threads. V1071. Calling the 'foo' virtual function in the constructor/destructor may lead to unexpected result at runtime. Using 'await' in a critical section may lead to a lock being released on a different thread. Abnormality within similar comparisons. V767. Subtraction, >, >=, <, <= should be applied only to pointers that address elements of the same array. MISRA. nlohmann/json.hpp:20925:5: warning: non-void function does not return a value in all control paths [-Wreturn-type], const_reference operator[](const typename object_t::key_type& key) const All I want the function to do is add one to the value of the each character inputted into the string array and shift it on the ASCII table and then return the coded message.
