I used to see someone writing c to oo, but the article always doesn't know the cloud, don't learn something, in fact, many C processes are also developed by OO's idea. So I summarize and I hope to discuss the OO method of C.
C is actually a very free language, while oo is a kind of thinking, and it is also a limit, as long as you add this limit in C, you can achieve a certain degree of OO.
For example, the most important thing in OO is package. The biggest feature of C is open. But if there is a packaged thought to write C, it is not possible.
In C , our class is said (with class a):
Class A
{
PUBLIC:
Function1 ();
Function2 ();
Private:
INT I;
Int J;
}
And I want to write such a package code with C (I can only say that there is a clear sign) is this:
Struct C_A_
{
INT I;
Int J;
}
TYPEDEF C_A_ A;
CA_Function1 (A *, other parameters);
CA_Function2 (A *, other parameters);
When you use it, you will have a big problem.
Then inherit, we must of course use a simple way to complete C so powerful inheritance, but it is not difficult to do inheritance, such as:
Struct C_B_
{
A a a;
Int m;
Int n;
}
TYPEDEF C_B_B;
CB_Function1 (b *, other parameters);
CB_Function2 (b *, other parameters);
Use when you are using a function:
CA_Function1 (& (B.A), other parameters);
CA_Function2 (& (B.A), other parameters);
This is just two major problems, but the polymorphic problem is not easy to think about the solution. Please discuss this feasibility of this visit.
I think OO is actually a way. We can also write a very OO C code without technical support.
