Silent suppression of exceptions can hide the presence of bugs in source code during testing. Consider inspecting the expression. The SUCCEEDED or FAILED macro should be used instead. Check lines: N1, N2. Likewise, report_ratio returns void, so we don't save its return value, either. The parentheses around the return expression in square are evaluated as part of the expression, and aren't required by the return statement. MISRA. Use a plain return statement to make your intent clear. V1082. V1073. The first call to printHi() is called in a context that does not require a value. Consequently, putting an empty return statement at the end of a void function is redundant: Do not put a return statement at the end of a non-value returning function. V766. Inappropriate attempt to append a null character to a string. Expression is equivalent to moving one unique pointer to another. AUTOSAR. V6013.

Further, testing by changing the function return type to int and changing the returns to 0 in the then code, 1 in the else if code, and 2 outside that shows assembly code that only returns 0 or 1, proving GCC was not just collapsing the third path into undefined behavior; it outright eliminates it because it is not possible. V3112. The expression contains a comma. V563. V532. Recurrent serialization will use cached object state from first serialization. Throwing from exception constructor may lead to unexpected behavior.

How can I control PNP and NPN transistors together from one pin? Comparing objects of incompatible types. MISRA. V3182. Member operator[] of 'foo' class has a 32-bit type argument. Shift by N bits is inconsistent with the size of type. Consider using the extended version of the 'foo' function here. The report_square function has a void return type, so it doesn't have an expression in its return statement. V3033. . : .'. A pattern was detected: A || (A && ). Two or more case-branches perform the same actions. The expression is incorrect or can be simplified. V632. Unexpected function overloading behavior. Unsafe invocation of event, NullReferenceException is possible. Giving short names to global variables is considered to be bad practice. V2501. The 'if' 'else if' construct should be terminated with an 'else' statement. Passing the value into the 'Foo' method will result in an exception.
