Re: funzione inline

Well:
----- main.c file ---
"main.c"? Really? Not "main.cpp"? Are you compiling it as C or as
C++? Well, I hope that you use C++. I'll assume you do.
#include <stdio.h>
#include <stdlib.h>
#include "Multiplication.h"
int main()
{
int f1, f2, prodotto;
printf("Inserire un valore intero per il primo fattore:\n");
scanf("%d", &f1);
printf("Inserire un valore intero per il secondo fattore:
\n");
scanf("%d", &f2);
Multiplication obj;
OK, so here you define the object 'obj'.
prodotto = obj.molt(f1, f2);
And here you use its member function. OK.
printf("Il prodotto tra i due fattori e\' %d\n", prodotto);
system("pause");
return 0;
}
----------Multiplication.cpp file----------
#include <stdio.h>
#include <stdlib.h>
#include "Multiplication.h"
inline int Multiplication::molt(int a, int b)
Why 'inline'? How should the compiler make use of that 'inline' here?
You should *only* declare some functions 'inline' if they are defined in
the *header*. For now, while you're still learning, try to follow that
rule or simply forget the keyword 'inline' exists if you want to define
your functions in separate translation units.
Drop the 'inline' from here, and you should be fine.
{
int result;
result = a * b;
return result;
Why not simply write
return a * b;
and drop the 'result' as unnecessary?
}
----------------Multiplication.h file----------------
class Multiplication
{
public:
int molt(int a, int b);
};

Who help me in finding out all the errors in my source files ?
See above.
