design - Why does the C++ standard still allow uninitialized primitive . . . If reading uninitialized memory is undefined behavior anyway, why has the C++ standard not been changed so that objects of primitive type (int, unsigned, float, double, bool, char) get default-initialized to 0? I see two important reasons compatiblity with past specifications of C++ (e g n3337) and past implementations (compilers like GCC)
What is the difference between uninitialized object variable and object . . . What's the reason? Class fields can be modified by any method In any order the method is invoked All non-private fields may be modified by other classes and or classes extending that class Hence, there is no point in notifying about an uninitialized variable, since it may be assigned in many, many places

Variable is uninitialized - SAS Support Communities But nevertheless, when you get the message that the variable is uninitialized, you need to look at your data with your own eyeballs, using PROC PRINT or viewtable, or any other way to display the data its When you look at work abc1 and work abc2 AFTER PROC IMPORT (not after the DATA step) in this manner, the problem will be obvious --
