Maybe he was only trying to help in he’s own way. As learners not everyone helping know what they’re saying

Absolutely my point, he is having a hard time understanding simple English

There’s no need to get mad brother Just understand an accept the fact that he was trying to help But the help he provided wasn’t enough, and your both good 😊

okk

Wtf is going on here

need a dev to code please

yes please

Code real world projects?

are you able?

I have some kind of message bus in my application and i need to track several int values at once. But this bus just for float type values. Is it save enough to reinterpret float as 4 uint8_t numbers? Or it depends on OS primitive sizes or something else?

Is there some safe way? I need only two uint8_t btw

在一个相当奇怪的时钟的表面上，小时数是从 1 到 12； 此时短针和长针都指向12。短针每小时顺时针移动2个数字，长针每小时顺时针移动3个数字。 多少小时后两根指针会再次指示相同的数字？ (一) 8小时 (b) 15 小时 (c) 指针再也不会指示相同的数字 (d) 12 小时 (e) 19 小时

Is there any way that my decimal number will store only number like this - 456.5457

Can anyone know any method of how i can take only 4 digits after decimal point for calculation in our code in decimal datatype

Is there any way for this

you can either have floating point or you can have whole number

you can either have floating point or you can have whole number

Actually in floating point the case is same i want it takes some garbage values after actual values in after decimal numbers

floating points just divides the number, you cannot just do some calculation on part of the number

Actually if you take flaoting point numbers like below Float a = 456.5478 it shows you while you debug the code as a= 456.547791

hi i don't understand why are you interested in what precision debugger shows you, i think based on IDE you are using there are ways in the IDE's settings to show you specific number of digits after decimal point. but if you want a specific precision in your calculations float point is not your best choice. float points are based on IEEE 754 standard which is composed of sign bit, mantissa part and exponent part and based on your value uses the best precision and rounds it. if you want a specific precision in your calculations you better use fixed point arithmetic. and if you are interested in number of digits on console you must use iomanip library using fixed and setprecision(4) methods. google it. i hope it clear things a bit for you.

I know for console we have set precision method but i want to store only 4 digits after decimal point in a float or double variable

Is there any method for this

Hello friends you have a complete binary tree training resource do you?

Hello friends you have a complete binary tree training resource do you?

D45 sent a huge message, it has been re-uploaded as a file hello i want to write a project, in which i want to use same class function in the another class..

Hello guys. Is there any way to use vector of different object types but same parent class?

can anybody help me with this?

You added definitions for new functions, instead defining your functions of the class, it should be something like this instead: int someClass::functionOne() { ... } void someClass::functionTwo() { .. }

hello i want to write a project, in which i want to use same class function in the another class function is it possible? for example: class someClass { public: int functionOne(); void functionTwo(); }; int someClass::functionOne() { // some code functionTwo(); // how to do this? // some code } void someClass::functionTwo() { // again some code }

You didn't add someClass:: for the second function definition. But you call it the right way

not asking for "someClass::" part, i told you above. asking for how to call a class function, into another function of the same class, and on normal call inside func definition it throws error: qualified name is not allowed.

The way you wrote it

If you want to access them only through virtual functions base class, you can store them as unique_ptr to base class. Otherwise you can store them as std::variant or std::any

Are you sure you don't add the prefix for the declarations? Are you sure your real code looks the same way as the example?

i cant send you the full code cuz the slow mode is enabled, but can dm you you for this if you want

This code compiles and works https://wandbox.org/permlink/JnhMxJ2skJ3M9ftu

not for me, may i send the code for you?

No, no need to. Just check that you don't have the prefix in your function declarations inside the class. Note that in the error the compiler prints there's the line number printed where the error occured, you need to check that line.

anyway i will try to send my code in here, you can run it and see i throwes error
