Hi,
I am getting error on doing multipal inheritance.
Please check the below code-
class Hal
{
public:
virtual int SetPrintLoss()
Type 'void' here ^^^ instead of 'int'.
please suggest me what to do now.
Enable warnings and pay attention to those. Most compilers warn that
Hal::SetPrintLoss() does not return anything despite being declared
int.
Thanks.
Agreed, Now Hal::SetPrintLoss() is returning 0.
the change code is -
class Hal
5 {
6 public:
7 virtual int SetPrintLoss()
8 {
9 cout << "Hal::SetPrintLoss" << endl;
10 return 0;
11 }
12 };
13 class FluxGrid : public Hal
14 {
15 public:
16 void SomeFunction()
17 {
18 cout << "FluxGrid::SomeFunction" << endl;
19 }
20 };
21 class HalAmplifier
22 {
23 public:
24 virtual void SetPrintLoss()
25 {
26 cout << "HalAmplifier::SetPrintLoss" << endl;
27 }
28 };
29 class Simulator : public FluxGrid, public HalAmplifier
30 {
31 public:
32 virtual void SetPrintLoss()
33 {
34 cout << "Simulator::SetPrintLoss" << endl;
35 }
36 };

It is very clear what is happening, please need some suggestion .
