C why getters and setters

You bring this up only after I give you access to Wonderland network and Rust project? It was just a theoretical question, Teo. I meant that you should not distinguish so much between humans and machines. Think of it as being from different countries," Noname explained. It'll impress the teacher if I already know what they're talking about.

Noname began "You've already used a construction where you have a private field and two methods to get and set the value for that field. Does this code look familiar to you?

Take a look at how I rewrote the same code above, using properties this time. But wait, Noname; I don't see any methods," I said. You don't see any methods, but the compiler does. This code snippet is treated by the compiler just the same as the previous code snippet. Then use the property the same as you do a field. Think of it as a field with 2 additional methods - get and set. Here are some exercises for you. Do not add any access modifiers to getters or setters.

Create a class ChickenFarm with 4 public properties: double Longitude , double Latitude , int Capacity , and string Identifier. Make a setter for the Identifier - private. Remove the setter for the Capacity. Leave all other getters and setters as-is without any access modifiers. Inside main , we create an object of the Employee class. Now we can use the setSalary method to set the value of the private attribute to Then we call the getSalary method on the object to return the value.

Yet it is possible to write an object-oriented program in any language, for example in C. Similarly, your program will not automagically get a proper OO design just because you wrote it in Java, or because you used certain language keywords.

The way you implement private encapsulation in C is a bit more crude than in languages with OO support, but it does like this:. This is how every reasonable C program out there is written.

And has been written for the past years or so, as long as program design has existed. C code compiled with only this declaration in scope can not access any hypothetical members of the struct, and can't use value of type Context either. But it can still handle pointers to Context values, so functions like these are possible:. This pattern insulates the client C code from any changes to the size or internal layout of Context. Note that this is a stronger guarantee than simply declaring but not documenting the members: Even if the programmers duly ignore the undocumented members, by-value use of the struct is permitted and will certainly slip in , and now the code has to be recompiled when the size changes.

In other words, opaque types only handled through pointers give greater ABI stability. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Learn more.
