First off, every program starts with a "problem".

In C, these problems are broken down into functions(or methods) to solve these problems. Each function is usually quite short, and has a specific task. Structures are the tools to store your data with C. Throughout a C program, you'll build up many structures designed specifically to hold data for certain items within your programs, and your functions all throughout. This is procedural programming, everything is broken up into procedures so a problem can be more simply solved.

In C++, the structures and functions are combined into one: the object. In object-oriented programming, problems are broken down in a way objects can be made to match real life objects. You start this by using a class. a class can hold variables and methods, and the data can be private, public, or protected. With this, you could have a class Dog, then you could declare the dog Bash, and with the appropriate functions and data members you can make him bark, wag his tail, and so forth.


I hope this helped people who want to know the difference between these two languages. If I said something wrong, please tell me, or if there's something to include, also inform me.

This probably wasn't necessary but I was bored as hell xD

technically you can make structures with functions as member variables in C aswell.
and you can also make data in structure "private". and actually you can also do pseudo inheritance with C.
the only thing that C cant do exactly is polymorphism. and honestly. i have never had the need for polymorphism, infact i dont
think i have ever used it other then trying some code out of a book.

im not sure what you are trying to say. can you explain better. i dont know where you get virtual functions from.

if you declare a function in a base class virtual, you can use overrided functions in the base class.

class A {
 do();
}
class B : public A {
 do();
}
fn (A& aobj) {
 A.do();
}
B bobj;
fn(B)

and polymorphism.
