Modules and Member Functions
I have 3 files: stack.h, calc,c and stack.c
Code:
void make_empty(void);
int is_empty(void);
int pop(void);
Code:
#include "stack.h"
main() {
make_empty();
...
}
Code:
#include "stack.h"
int contents[100];
int top = 0;
//function definitions
I get that stack.h is the interface, calc.c is the client and that stack.c is the implementation of the module. My question is: What exactly is the module? The definition is "a collection of services", so I thought that would be stack.c, but it isn't?
Also if you can access data members of a structure using the . and -> operator, why can't you use it with objects and member functions?
Code:
struct blah{
int a;
int b;
};
blah *abc;
abc->a = 0;
Since -> means (*abc).a, why can't you use it when calling member functions outside the class?
Code:
class Fraction {
int denom;
int num;
public:
void reduce();
};
Fraction *f1, *f2;
f1->reduce();
