An mistake means that the function can't attain its advertised function (which include developing postconditions).
Below, vector and strings constructors may not be able to allocate ample memory for their factors, vectors constructor may important site not be equipped copy the Issues in its initializer record, and File_handle will not be capable of open the expected file.
