Questions about C

post #1 of 7
Thread Starter 
So Im learning java and c somewhat simultaneously I started with java first but needed c for a project at school. I know that java is object oriented and that c is not but looking at some of the ways that you cad code lua using c the people who made the code have things such as class gui = guiclass protected. Does this mean that one can create objects in c? Or does c have some sort or class system in which you can call instance methods from a main function? If anyone can give me some reading material on this please do im greatly interested as c offers some benefits that i would like to take advantage of over java.

Yes, but it's not exactly straightforward, especially if you're new to C.

Is there a reason why you cannot use C++?

afaik you can make objects in C... for example you can create structures, which are pretty similar to classes (in fact they are functionally the same, except they are public by default)

but that doesn't make C an object-ORIENTED programming language.

Sure, you can be object oriented in C, but you have to do a lot of the work that's since been offloaded to the language and compiler in C++.

For an example, see gtk+ and glib, the largest project(s) I can think of that use C in something like an object-oriented manner.

the reason im asking is because for a student group ive joined im using a micro controller to make a driver display for a race car and the controller can only be coded in c if it was java there would be a lot of nicely complex structures and objects everywhere but in c im just leaving and my code is very long where it should not be so i saw that and had hope that i may easily be able to create large structures similar to those in java. If you have 2 strucs in c can you do (like in java) object.getSize(); is there the equvalent of instance methods in c when using multiple strucs?

In C you can use the sizeof keyword

Code:
struct StructOfStuff
{
    int myInt;
    bool myBool;
}

int main()
{
    size_t structSize = sizeof(StructOfStuff);

    return 1;
}
