With widening conversions, we are converting to a data type that occupies more storage space in memory than the data type we are converting from. (https://uops.info/ and https://agner.org/optimize/). Why does bunched up aluminum foil become so extremely hard to compress? rev2023.6.2.43473. C and C++ compilers can use movzx when widening a bool to an int because the object-representation of a bool is guaranteed / required by the ABI to be 0 or 1. The content must be between 30 and 50000 characters. In a system where the conversion could have an impact the most efficient way is to not convert and to keep trues and falses as target type (int or byte, etc.). Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.

I assume you meant == here. To learn more, see our tips on writing great answers. This is known as a standard conversion. int i = 50; long lng = 100; i = (int) lng; // Cast to int. This is a widening conversion since we are converting from a type that occupies 4 bytes of memory (an int) to a type that occupies 8 bytes of memory (a long). But python itself has a rule saying "anything has a boolean interpretation": empty collectios, 0, the empty string are False, anything else True, so you can do mylist = [] if mylist: something. Cannot implicitly convert type 'type' to 'type'. @Joseph I don't think it's understanding how it works is the problem they were preventing. This kind of double nature allegedly frequently leads to problems and it makes the code less readable (since you have to judge from the context whether a given usage of an int is intended as int or bool). Does the C++ standard allow for an uninitialized bool to crash a program? dFirst <= iSecond is returning a bool value which cannot be converted to an int - iThird. Please. This is even worse than if(a==b) total++; which does compile the way you'd expect. I am unable to understand that I have declared array as boolean variable and there is no other int variable in my code and it doesn't matter what my function arguments are right? Fair enough, that is the one he asked about just pointing out that there are other problems in the code too so the OP doesn't think that fixing that will automatically make the program work correctly.

We get a movzx-load if we take a pointer-to-bool that's not already in a register: There were some questions raised in comments about which is actually better. I don't think the issue is some much about true/false or 1/0 as it is about the decision to make C# a strongly-typed language rather than a weakly-typed language. Are non-string non-aerophone instruments suitable for chordal playing? I've never had a difficulty understanding the switch statement construct in the C++ sense, but I guess I can see why others might find it conceptually easier the C# way. The third line of code tells the compiler to explicitly convert the variable lng, which is of type long, to an int before making the assignment. /tmp/cc1LNGYB.o: In function `test::t()': By not allowing things like if (27) the language forces people towards a syntax that is more reliable like: if (27 > 0). To see how data loss can occur, consider the following sample: The variable lng now contains a value that cannot be stored in the variable i because it is too large. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. You can use true instead. class.cpp:(.text+0xb0): undefined reference to `std::cin' In this case, you can just do "else" - if first isn't greater than second and they're not equal, then obviously second has to be larger. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Can I takeoff as VFR from class G with 2sm vis. the if (i=1) it's possible in C because the assignment operator return a value (useful if you want to do a = b = c = 5) for example, Python is strongly typed AND the assignment it's a statement, and doesn't "return" nothing. You can use true or false instead. This is not possible in the C# language. This time the variable lng is on the left-hand side of the assignment operator, so it is the target of our assignment. if (5 > 0) is easier to understand rather than if (5) It's the same reason why they don't allow fall through conditions in switch statements. Hyperconverged All-in-One Streaming Engine, ushering in new age for distributed database. class B {} // Convert bool to int. You can use true or false instead.

Connect and share knowledge within a single location that is structured and easy to search. I wouldn't be too optimistic; I'd guess probably still materializing a bool into a register and adding it. It's too easy to make a mistake. Remember that with a narrowing conversion, there is a potential loss of data. The hunt is for the following assembly which is generated by the GCC: I think it helped a bit (see the comments in code). Can I also say: 'ich tut mir leid' instead of 'es tut mir leid'?

To get the code to compile we would need to use the following syntax: The third line of code tells the compiler to explicitly convert the variable lng, which is of type long, to an int before making the assignment. Making statements based on opinion; back them up with references or personal experience. This is very much a missed optimization in current C# implementations; that branching asm is insane, IMO. I think the problem is the architecture desicion "true is true, not any number != 0" (C++) and I was wondering what the benefits of such an architecture are? If we were to convert this value to an int type we would be losing some of our data and the converted value would not be the same as the value before the conversion. A bool can be converted to 0 or 1. Asking for help, clarification, or responding to other answers. If C were strongly-typed the result of the assignment would be disallowed in this context, as it is in C#. Sam Allen is passionate about computer languages. @PMF this asm was generated in Release mode. When working with value types you work directly with the data stored in the variable.
