Hello , Would Anyone Here tell me What is the main Purpose of int main()? Why using int before main()?

We use it so as we may have an interger based output for c++ code

For c++ code? Or c code

We use it so as we may have an interger based output for c++ code

Ok i understand but even using this function we also use charater dataype to print a character and strings ??? So why we dont declare a char main()?

Hope other programmers will give an additional opinion

Hey guys! How do i write a c++ program that output the sum of 2 numbers which is equal to the number i input? The sum cannot have 3 in it🤔 But the input can

Hi all! I created one class and derived it from two. Now I can't create an instance of that class because it's abstaract. How can I use methods from two classes in one class?

i didn't understand your question But maybe you'll get something from this example: class A { public: void test(){} }; class B { public: void test(){} }; class C : public A, public B { }; void foo() { C c; c.A::test(); //calling test A c.B::test ();//calling test B }

I thought you were answering me 😢

Could you please take a look at that?

Here it is

Thx. I understood my problem. I tried to derived from one normal class and second was abstract. That why I can't create instance.

Sorry I got -what I call- Cphobia Which means I hate to look at C codes So I can't help you a lot

Why you have Cphobia?

Soon I start reading a C code my head goes dazing

C has a real bad code base

Which language you like most?

C has a real bad code base

how a language like C can have a code base?

it's really hard to read a C code unless you have some previos experience and level 100 of patients

But I can't develop Linux kernel by C++. C is needed for that

Hmmm C is a subset of C++ so...

It's true, learning C is the most arduous work to do.

to me they are different languages

and the philosophy it's completely different

C really put you on risk(shooting your foot) unless you are 100% focused

I have no problem with C, only thing are strings in C are pain.

but you can have your string "class" too

String Class? There are no classes in C I think.

but you can code object oriented c and have pimpl pattern
