An exception handling block does not contain any code. Execution resumes in the calling function at the point immediately following the call. V674. The 'std::uncaught_exception' function is deprecated since C++17 and is removed in C++20. Lifetime of the heap-allocated variable is limited to the current function's scope. V3162. V3036. The compiler makes no such assumptions, so you need to make sure that there is a return path that will be followed if the return statement inside your loop is never reached. The expression contains a suspicious mix of integer and real types. MISRA. GCC options: warning on non-void functions without a return statement, Type No return, in function returning non-void, no return in function using switch statement, No return statement warning in function returning non-void. MISRA. A return statement (with no return value) can be used in a void function -- such a statement will cause the function to return to the caller at the point where the return statement is executed. Constant expression evaluation should not result in an unsigned integer wrap-around. Return value of function is written to N-bit variable. Consider inspecting the expression. C compiling Error: non-void function does not return a value in all control paths - CS50. The function with the 'atof/atoi/atol/atoll' name should not be used. If a function returns no meaningful value, it should be declared with return type void. Silent suppression of exceptions can hide the presence of bugs in source code during testing. Buffer needs to be securely cleared on all execution paths. V3549. V3172. V639. V726. V3044.

V6104. It is more efficient to use an initialization list rather than an assignment operator. Logical literal belongs to second operator with a higher priority. Potentially tainted data is used in the path toextractthe file. The 'if' 'else if' construct should be terminated with an 'else' statement. Potentially tainted data is processed by regular expression that contains an unsafe pattern. V3521. It is possible that these are misprints and 'default:' label should be used instead. Function exited without releasing the pointer/handle. Recurrent serialization will use cached object state from first serialization. V573. V1049.

Content Discovery initiative April 13 update: Related questions using a Review our technical responses for the 2023 Developer Survey. A function that does not return a value is called a non-value returning function (or a void function). Why does Acts not mention the deaths of Peter and Paul? The other function parameter expects a file path instead. Initial and final values of the iterator are the same. V6002. WPF: several Dependency Properties are registered with a same name within the owner type. V518. It's better to use '= default;' syntax instead of empty body. V744. V5613. Suspicious subexpression in a sequence of similar comparisons. V6060. V6078. The loop counter should not have floating-point type. V3085. The ratio function returns the ratio of its two int arguments as a floating-point double value. Consider using an explicit type cast to avoid overflow or loss of a fractional part. If a function sometimes forgets to return a result, you will get a warning (if you have requested warnings). Calling overrideable class member from constructor is dangerous. The second condition is always false. Use direct analyzer integration or compiler monitoring instead. How can I control PNP and NPN transistors together from one pin? The 'throw' keyword could be missing. Possibly, it was intended to be escaped. It is possible that the variable should be used instead of the string literal. Two 'if' statements with identical conditional expressions. Strings were concatenated but not used. Execution of report_ratio "falls off the bottom" and returns no value to the caller. Consider adding '[Flags]' attribute to the enum. V118. Compiler may optimize out this loop or make it infinite. V1020. OWASP.

To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. MISRA. The result of the right shift operation will always be 0. V818. Suspicious expression 'A[B < C]'. Non-void functions always have to have a return statement. Use filter buttons or 'Don't Check Files' settings to enable message display. Does this function have explicit return values on all control paths? Subtraction, >, >=, <, <= should be applied only to pointers that address elements of the same array. Collection is modified while iteration is in progress. An identifier declared in an inner scope should not hide an identifier in an outer scope. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. V2605.

V6068. Function exited without performing epilogue actions. If certain compiler flags are passed, this type of error or warning might get suppressed entirely, which will lead to run-time faults if the given function gets called in the program. Inconsistent synchronization of a field. Examine the substrings "abc" and "abcd". V3548. Why typically people don't use biases in attention mechanism?

Potential logical error. V6073. The object was used after it was verified against null. Use volatile variable(s) or synchronization primitives to avoid this. An alternative would be to have the default setting of Wreturn-type depend on flag_isoc99. If the function has a void return type, this behavior is okay, but may be considered poor style. Use of 'Foo' named constant with 0 value in bitwise operation. However, C doesn't require the parentheses. Decreased performance. V6094. For example: In the above program, the value to be printed needs to be provided on the right-side of the std::cout <<. V642. A code fragment from 'file' cannot be analyzed. In such a case, the comparison operation may behave unexpectedly.
