For example if you write a code in C++ with C style or C# style, the code will be considered bad because this languages have different idioms for writing code

Is there any place that has those idioms organized well for learning ?

From where should i learn c++ ?

C++ Core Guidelines, Mayer's books

Ok

What is wrong with line 13 ? X is a float value

Does learning computer science theory is necessary for writing good code?

#include <stdio.h> int main() { int a= -1,b = -a; int x,y; x = (a> 0) && (b < 0) || (a< 0) && (b > 0); y = (a<= 0) || (b >= 0) && (a>= 0) || (b <= 0); printf("%d\n",x == y); return 0; }

#include <stdio.h> int main() { int a= -1,b = -a; int x,y; x = (a> 0) && (b < 0) || (a< 0) && (b > 0); y = (a<= 0) || (b >= 0) && (a>= 0) || (b <= 0); printf("%d\n",x == y); return 0; }

modulo(%) is not applicable to float and double numbers.

It is not but it helps

Then how to write it

Don't agree, if u write code on c++ computer science is necessary

in c: include math.h and use remainder function in c++: include cmath and use std::fmod function

And why is that?

Because this's C++, not Java or C#. This language is about low level mechanisms as C but unlike to C give u instruments to make abstractions - OOP. Without knowledge and understanding computer science u can't programming on C++ effectively and also can make more mistakes in ur code which 'll be harder to fix by own.

1) Object-Oriented Programming is not the only language feature to write abstractions in C++ 2) Object Oriented Programming is main language feature to make abstractions in C# or Java 3) Object Oriented is not such a hard concept to learn without taking CS classes 4) You can do a lot of low level stuff in C# (pointers, SSE/AVX operations)

All C++ knowledge I have I didn't get from my university I learnt myself

But Java 'n C# is VM dependent and if there's not JIT this two 'll be very slow

Because most of universities in UNG are bullshits

C# Mono compiler uses LLVM as C++ clang compiler as a head of time compiler and also have JIT compiler.. so in some cases it can be faster than C++ :) Not in general case sure

In some very rare cases. Anyway, knowledge about cs is necessary if we talking about c++

I do not like this statement If you want to learn, you'll get knowledge in the world worse uni

All these concepts you guys speak about, like llvm and stuff , you learned from cs classes?

You didn't provide ANY reason why :)

1) What mistakes? 2) You can understand what you're writing without CS classes :)

Anyone looking for a student 😐

1) Memory management, if u don't know what is mostly use runtime time (what?) how u can write code effectively

Everything you are talking about can be learnt without CS classes

Like ?

I won't learn cs in University because where I live it's too expensive but I really want to learn,it's very hard to sort your learning map without any advices

Please tell the exact statement in c I don't know how to use the remainder function

#include <stdio.h> #include <math.h> main() { double x=2.5, y=1.1; printf("rem:%f\n", remainder(x, y)); return 0; }
