No problem with that. But without the information I'm asking, it's going to be difficult to help you.

This is the compile output(i hope it helps):

Where are these methods implemented ?
-
I've implemented the methods into the main file, and i create an header file in witch i declared the variables.
@Gabry80 In order to give help it would be necessary to see the code from main (main.cpp / main.h)
-
This is the pointer1.h (Header file)
#ifndef POINTER1_H
#define POINTER1_H#include <QMainWindow>
int sommaVal(int a, int b); //parametri passati per valore
int sommaPun(int *a, int *b); //parametri passati per puntatore
int sommaRif(int &a, int &b); //parametri passati come indirizzonamespace Ui {
class Pointer1;}
class Pointer1 : public QMainWindow
{
Q_OBJECTpublic:
explicit Pointer1(QWidget *parent = 0);
~Pointer1();private:
Ui::Pointer1 *ui;
};#endif // POINTER1_H
And, this is the Main.cpp
#include "pointer1.h"
#include <QApplication>
#include <string>
#include <iostream>using namespace std;
int main()
{
int a = 5;
int b = 4;
char carattere;
int rrr = sommaVal(a,b);
cout << "Risultato(Val)=" << rrr << endl;
cout << "a =" << a << endl;
cout << "b =" << b << endl;
cout << "-----------" << endl;
rrr = sommaPun(&a,&b);
cout << "Risultato(Pun)=" << rrr << endl;
cout << "a =" << a << endl;
cout << "b =" << b << endl;
cout << "-----------" << endl;
rrr = sommaRif(a,b);
cout << "Risultato(Rif)=" << rrr << endl;
cout << "a =" << a << endl;
cout << "b =" << b << endl;fflush(stdin); scanf("%c", &carattere); int r; r = a+b-1; a = 3; b = 6; return r;/* int s = *a+*b-1;
*a = 3;
*b = 6;return s;*/
int t = a+b-1;
a = 4;
b = 6;return t;}

Where are the bodies ?
Like
int sommaVal(int a, int b) {
..code...
}
seems not to be in main.cpp ?
