Question

I want to reproduce a get style function from C++ in a C program. In C++, there can be two functions in a class for assigning the value and setting the value. Is there any equivalent way in `C? Lets say i have following structure:

typedef struct test_help
{
    int      a;
    void** numArrays;
    struct test_help *next;  
} help_node, *help;

I have function like the following for accessing the value of structure:

int access_int(help damaru) {
    return damaru->a;
}

so I can assign the value of integer from the structure:

 int y = access_int(damaru);

But i want to assign the value to the memeber of structure like:

help damaru;
int z=10;
damaru->int = z;

I would like to get rid of the use of ->. I would like to write a function which is similar to the assign function. I would like to remind you that use of access function in left hand side shows warnings.

Answer 1

You have a typo that is why you get a syntax error, the correct way to do this is

 damaru->a = z;

To make an access function something like this would work

 void setA(help inHelp,int inA)
 {
    inHelp->a = inA;
 }

Then use

 setA(damaru,z);

Remember you are using C. C is not object oriented so there is no direct mapping of this object oriented feature.
